test(gate): fix the last 4 readiness/config false-fails (none are product bugs)

On a proper on-node .228 run (synced bitcoin, 4-fix binary) the lifecycle matrix is
green; these 4 were test-harness issues:
- lnd 'recovers after restart' (65): bump retry window 90s->240s. lnd cold-restart
  recovery (wallet unlock + bitcoind reconnect + graph sync) exceeds 90s on a loaded
  node but DOES complete (synced_to_chain:true).
- bitcoin ui responds (89): retry ~120s instead of single-shot (companion nginx may
  have just been recreated by the companion-survives test).
- probe_app_url (99 lnd proxy + all ui-coverage proxy probes): retry up to 90s for
  post-restart proxy/UI readiness instead of single-shot.
- required endpoints after restart (94): :8081 is nginx-proxy-manager, an OPTIONAL
  app (not in required_containers) — only assert it when NPM is installed; and make
  the trailing lncli getinfo a retry.
