fix: harden OTA updates, AIUI desktop gap, LND no-proxy

- update.rs: post-OTA probe falls back to http://127.0.0.1/ on connect
  error (nginx binds :80, not :443) so good updates are no longer rolled
  back; recover stuck update_in_progress; avoid ETXTBSY on running binary
- LND: REST client bypasses proxy, GET newaddress p2wkh, wallet
  readiness/unlock after restart
- Dashboard.vue: chat route back to plain h-full (desktop bottom-gap fix)
- vite.config.ts: dev-only /aiui proxy
- tests/release/run.sh: release gate harness (static+frontend+backend)
- CHANGELOG: v1.7.89-alpha notes
