test: gate that LND wallet is unlocked after restart (catches fleet-wide lock)

A wrong/locked LND wallet password leaves the wallet LOCKED after every
restart/OTA, breaking all Bitcoin-receive + Lightning ops fleet-wide — and the
harness was blind to it: live-lnd-address-type treats 'wallet locked' as PASS,
os-audit treated lnd-unreachable as WARN, and the archipelago lnd.getinfo RPC
masks a locked wallet (returns all-zero success).

- tests/release/run.sh: new 'live-lnd-unlocked' stage polls LND's unauth
  /v1/state and FAILs if still LOCKED after a 60s grace window.
- tests/lifecycle/os-audit.sh: probe lnd.newaddress (the real receive path,
  which surfaces LND_WALLET_LOCKED) instead of lnd.getinfo; locked = hard FAIL,
  not-installed = WARN.

Proven on .116 (genuinely locked): os-audit now reports
'[FAIL] lnd wallet unlocked (lnd.newaddress) wallet LOCKED'.
