feat(openwrt): add OpenWrt gateway status view and get-status RPC

Backend: new `openwrt.get-status` RPC endpoint SSHes into the saved (or
provided) OpenWrt router and returns system info, TollGate config, and WiFi
AP interfaces via UCI.

Frontend: new OpenWrtGateway.vue view at /dashboard/server/openwrt shows
system hostname, OpenWrt version, uptime, TollGate install/enable state with
pricing and mint URL, and all AP-mode WiFi interfaces. Linked from the Local
Network section of the Server view.
