fix(ui): stop sending an empty ssh_password over the saved router connection

provisionTollgate/saveTollgateConfig/scanWifi/configureWan all fell
back to the Connect form's local refs (host/sshUser/sshPassword) when
connectedParams was null. Those refs only get populated if the form
was actually submitted this session — on a normal page load the
router reconnects via the server-persisted config instead, leaving
sshPassword at its default ''. Sending that as an explicit
(empty-but-present) ssh_password overrides the backend's saved-config
fallback, so every action auths with a blank password instead of the
real saved one.

Added authParams(): omit host/ssh_user/ssh_password entirely unless
connectedParams is actually set, same as the status poll already does.
Caught live: dropbear on archy-x250-pa3's router logged a single bad
password attempt at the exact moment "Install TollGate" was clicked,
sandwiched between periodic status-poll connections succeeding with
the real saved password.

+# OpenWrt Gateway Setup
+
+How to connect an OpenWrt router to an Archipelago node and, optionally, turn
+it into a pay-as-you-go WiFi gateway with **TollGate**. Written for a node
+operator following the UI; a developer-facing RPC/architecture reference is
+at the bottom.
+
+This feature manages a **separate physical (or virtual) router** running
+OpenWrt over SSH/UCI — it is not a containerized app. Archipelago itself does
+not flash or install OpenWrt; you bring a router that already runs it.
+
+## What you get
+
+- **Status dashboard**: hostname, uptime, firmware release, WiFi interfaces,
+  WAN state — polled live from the router.
+- **WAN/WISP wizard**: point the router's radio at an upstream WiFi network
+  (turns it into a wireless bridge/repeater) with DHCP + NAT configured for
+  you.
+- **TollGate provisioning** (optional): installs the
+  [TollGate](https://tollgate.me) captive-portal package
+  (`tollgate-module-basic-go`) and stands up an `archipelago` SSID that
+  sells timed internet access for sats, settled against this node's local
+  Cashu mint.
+
+## Prerequisites
+
+1. **A router already flashed with OpenWrt.** Check the
+   [OpenWrt Table of Hardware](https://openwrt.org/toh/start) for your model
+   and follow OpenWrt's own install/flashing instructions — that part is
+   outside Archipelago's scope. See below for a worked example (GL.iNet
+   AX3000).
+2. **SSH reachable.** Fresh OpenWrt images enable `dropbear` (SSH) on LAN by
+   default, listening as `root` with no password (or the password you set
+   during OpenWrt's first-boot wizard at `192.168.1.1`). Archipelago
+   connects with `ssh2` over a password (key-based auth is supported at the
+   library level but the UI only offers password so far).
+3. **Same LAN as the Archipelago node**, at least for setup — plug the
+   router's LAN port into the same switch/network segment the node is on.
+4. **For TollGate**: a running Cashu mint app (`nutshell`/`cashu-mint`) on
+   this node — provisioning defaults `mint_url` to
+   `http://<node-ip>:3338` and TollGate customers must be able to reach that
+   URL from outside the node's loopback.
+
+## Worked example: flashing a GL.iNet AX3000 to stock OpenWrt
+
+GL.iNet's "AX3000" travel router is the **Beryl AX (GL-MT3000)** —
+MediaTek MT7981B (Cortex-A53), OpenWrt target `mediatek/filogic`. It ships
+running a GL.iNet fork of OpenWrt with its own web UI and LuCI already
+enabled, but the steps below replace that with stock/vanilla OpenWrt so it
+matches the prebuilt TollGate `.ipk` architectures exactly
+(`aarch64_cortex-a53`).
+
+1. **Download the sysupgrade image** for the current stable release from
+   `https://downloads.openwrt.org/releases/<version>/targets/mediatek/filogic/`
+   — the file you want is
+   `openwrt-<version>-mediatek-filogic-glinet_gl-mt3000-squashfs-sysupgrade.bin`.
+2. **Verify the checksum** against the `sha256sums` file in that same
+   directory before flashing anything.
+3. **Flash from the GL.iNet UI**: on the router's default address
+   (`192.168.8.1`), go to **More Settings → Upgrade → Local Upgrade**, or
+   open **Advanced → LuCI** and use **System → Backup / Flash Firmware →
+   Flash new firmware image**.
+4. Upload the `.bin` file. **Uncheck "Keep Settings"** — going from the
+   GL.iNet fork to stock OpenWrt needs a clean reset, not a config carry-over.
+5. Confirm and wait ~3–5 minutes without power-cycling the router.
+6. **After it reboots** you're on stock OpenWrt: LAN at `192.168.1.1`, DHCP
+   on, SSH (dropbear) open as `root` with **no password set yet** — set one
+   via LuCI at `192.168.1.1` or `passwd` over SSH before doing anything else.
+   From here, continue with the Prerequisites/Step 2 flow above to connect
+   it to the Archipelago node.
+
+**If the flash fails / the router doesn't come back**: filogic devices
+don't use a reset-button recovery. Instead, connect to the router's LAN
+port and, during boot, press a key within the first ~2 seconds to enter
+U-Boot; per the OpenWrt wiki, typing `gl` then `httpd` at the U-Boot prompt
+brings up a recovery web UI at `192.168.1.2` that accepts a firmware image.
+
+## Step 1: Open the OpenWrt Gateway panel
+
+1. In the Archipelago UI, go to **Server**.
+2. Under the network status list, click **OpenWrt Gateway**
+   (`/dashboard/server/openwrt`).
+
+If no router has been connected before, you'll land on the connect form.
+
+## Step 2: Connect the router
+
+You have two options:
+
+- **Detect**: click **Detect** — this reads the node's own active wired
+  Ethernet interface, derives its subnet, and probes every host on it for
+  `TCP/22` + a valid `/etc/openwrt_release`. If it finds exactly one router
+  it fills in the host automatically; if it finds several you pick from the
+  list. A `/24` scan can take up to ~2 minutes (255 sequential probes at
+  500 ms each on hosts that don't respond).
+- **Manual**: type the router's LAN IP (commonly `192.168.1.1` on a router
+  freshly bridged in, or whatever address it has on your network) plus the
+  SSH username (default `root`) and password.
+
+Click **Connect**. On success the panel switches to the status dashboard and
+the connection (host + credentials) is persisted server-side — you won't
+need to re-enter them on future visits or from other views (e.g. the Home
+dashboard's network tile also polls this without prompting again).
+
+> Credentials are stored in `router_config.json` under the node's data
+> directory alongside other node config. There's no separate secrets
+> vault entry for this yet — treat the router's SSH password like any other
+> node-local config.
+
+## Step 3: (Optional) Configure WAN/WISP
+
+Use this to make the OpenWrt router pull its internet connection from an
+upstream WiFi network instead of a wired uplink — useful for a
+battery/off-grid TollGate node or extending coverage from an existing
+network.
+
+1. From the status dashboard, start the **WAN setup** wizard.
+2. **Scan** — the router's radio scans for visible networks (a few seconds
+   of SSH round-trips).
+3. **Select network** — pick the upstream SSID from the list.
+4. **Password** — enter the upstream network's WiFi password (encryption
+   defaults to `psk2`; leave blank only for open networks).
+5. **DHCP / NAT** — review the LAN DHCP pool (default `.100`–`.249`) and
+   whether to enable NAT/masquerade on the WAN zone (leave this on unless
+   you have a specific reason not to).
+6. **Connect** — this writes a `wwan` STA `wifi-iface` + `network` interface
+   over UCI, enables the radio if it was disabled (OpenWrt ships with
+   `radio0.disabled=1` on a fresh flash), and adds `wwan` to the WAN
+   firewall zone.
+
+The dashboard's WAN panel shows the resulting association state, assigned
+IP, and whether the router currently has internet reachability.
+
+## Step 4: (Optional) Install TollGate
+
+Once connected (and with a local Cashu mint app running), the dashboard
+shows a **TollGate: not installed** panel with a single **Install TollGate**
+button — there's no config form at this stage, it installs with defaults.
+The panel itself warns: *"Router needs internet access to install TollGate
+— configure WAN above first"* (Step 3), since the router has to reach the
+internet to download the package.
+
+1. Click **Install TollGate**. The button relabels to *"Installing… this
+   may take a few minutes"* while it works.
+2. Under the hood this installs `tollgate-module-basic-go` on the router
+   (via `opkg` on OpenWrt ≤24.x, or a manual `.ipk` extract on 25.x images
+   where `opkg` isn't available), writes `/etc/tollgate/config.json`, and
+   creates the `archipelago` SSID — all with default pricing (10 sats per
+   1-minute step, minimum 1 step, `mint_url` auto-filled to
+   `http://<node-ip>:3338`, enabled).
+3. On success you'll see *"TollGate provisioned successfully"* and the
+   panel switches to the installed view (Enabled/Disabled badge, current
+   price/step/mint).
+
+### Configuring price, step size, or mint (after install)
+
+The installed-state panel has an **Edit** button — this is the only place
+you set price/step/mint, and it only appears once TollGate is already
+installed:
+
+1. Click **Edit**.
+2. Set **Price** (sats), **Step size** (minutes — billed as `step_size_ms`
+   under the hood), **Minimum steps** a customer must buy at once, **Mint
+   URL** (leave as the auto-filled node URL unless pointing at an external
+   mint), and the **Enable TollGate** toggle.
+3. Click **Save**. Changes are pushed to `/etc/tollgate/config.json` and the
+   daemon is restarted to pick them up — it does not hot-reload.
+
+Anyone who joins the `archipelago` SSID sees TollGate's captive portal and
+pays sats (via the configured Cashu mint) for timed access.
+
+## Reconfiguring or moving to a different router
+
+Use **Disconnect** on the status dashboard to return to the connect form —
+this only clears the panel's client-side state, it doesn't delete the
+persisted `router_config.json`, so reconnecting to the same router needs no
+re-entry. To point at a *different* router, disconnect and connect with a
+new host/credentials; the newly connected router becomes the persisted one.
+
+## Troubleshooting
+
+- **"No router configured"**: nothing has been connected yet, or the saved
+  config didn't include a host — go through Step 2 again.
+- **Connect hangs or times out**: the router isn't reachable on `TCP/22`
+  from the node's network, or SSH auth failed. Confirm you can `ssh
+  root@<router-ip>` manually from the node (or a machine on the same LAN)
+  with the same credentials.
+- **Router "moved networks" / stale saved host**: SSH/status calls are
+  bounded (5s TCP connect, 30s read/write) precisely so an unreachable
+  saved router can't stall other RPCs — but the dashboard will show a
+  connection error until you reconnect with the router's current address.
+- **TollGate provision fails with "No pre-built TollGate package for
+  architecture..."**: your router's SoC isn't one of the prebuilt
+  `.ipk` targets (`mips_24kc`, `mipsel_24kc`, `aarch64_cortex-a53`,
+  `aarch64_cortex-a72`, `arm_cortex-a7`). You'll need a custom opkg feed or
+  to build `tollgate-module-basic-go` from source for your architecture.
+- **TollGate download looks like it succeeded but provisioning still
+  fails**: the node sanity-checks the downloaded `.ipk` is at least 50 KB —
+  a smaller file usually means `wget` captured an HTML error page instead
+  (no internet access from the router, or a bad release URL).

+Backend crate: `core/openwrt` (`archipelago-openwrt`) — SSH/UCI plumbing,
+WAN/WISP config, WiFi scanning, and TollGate install/config. See
+[`architecture.md`](architecture.md) for where it sits in the workspace.
+
+RPC methods (`core/archipelago/src/api/rpc/openwrt.rs`, dispatched in
+`core/archipelago/src/api/rpc/dispatcher.rs`):
+
+| Method | Purpose |
+|---|---|
+| `openwrt.scan` | Probe a subnet for OpenWrt routers (`subnet`, `prefix`, `ssh_user`, `ssh_password`) |
+| `openwrt.get-status` | Full status: release, WiFi interfaces, WAN, TollGate state. No params → uses saved `router_config.json`; params with `host` also persist the connection |
+| `openwrt.configure-wan` | Write WISP/WAN config (`ssid`, `password`, `encryption`, `dhcp_start`, `dhcp_limit`, `masq`) |
+| `openwrt.scan-wifi` | Radio scan for visible upstream networks |
+| `openwrt.provision-tollgate` | Install/reconfigure TollGate (`price_sats`, `step_size_ms`, `min_steps`, `mint_url`, `enabled`) |
+
+Note: these are distinct from the unrelated `router.*` methods
+(`router.discover`, `router.configure`, `router.list-forwards`, ...), which
+handle UPnP/NAT-PMP port forwarding on the node's own upstream home router —
+not the OpenWrt gateway feature described here.
