feat(setup): Zeus lightning journey — fund-wallet step, IBD timer + finish-setup toast, channel suggestions

Every Lightning setup (Open a Shop, Accept Payments, Run a Lightning Node)
gains a guided path to a working channel:

- New "Fund Your Bitcoin Wallet" step, gated on the blockchain finishing
  its initial sync: while syncing it shows a live progress bar with a
  counting-down time-remaining estimate; once synced it shows the on-chain
  balance and a "Fund Wallet" button that opens the receive modal with a
  fresh address, QR, and the Zeus channel limits (min 150,000 / max
  1,500,000 sats) noted.
- When the sync finishes while a Lightning setup is mid-flight, a toast
  pops with a "Finish setup" link straight back to the wizard (toasts now
  support action links). If several setups are in flight, one is chosen —
  the shared steps complete the lightning part of any of them.
- Channel steps are Zeus-branded (logo + copy) and land on the Lightning
  Channels screen, which now carries an "Open a channel with Zeus" card
  that prefills the open-channel modal with the Olympus peer URI, 150k
  sats, and private-channel checked. "Get Zeus" links to zeusln.com.
- Setup completion now actually requires walking the manual steps (fund,
  open channel, configure) — previously any step whose app was installed
  was silently auto-ticked and running apps marked the whole goal done.
- Completion CTAs now go to the app you just set up ("Go to my shop
  (BTCPay)" etc.) instead of the generic services list; iframe apps open
  in the on-top app overlay.
- On-chain send modal gains a "Send all funds" sweep toggle, backed by
  LND's send_all on the backend (amount no longer required when sweeping).
- Demo/mock: bitcoin.getinfo now returns the block_height/sync_progress
  contract the UI reads and simulates a ~90s IBD ramp per visitor so the
  timer, toast, and fund flow can all be demoed live; channel list data
  fixed (status/channel_point/liquidity totals — the panel previously
  crashed on the missing status field); sendcoins supports send_all.
