fix: container stability, OnlyOffice removal, node bootstrapping, UI fixes

Container orchestration:
- Add --network-alias to all archy-net containers (fixes Podman DNS)
- Fix bitcoin-knots health check: expand $BITCOIN_RPC_PASS at creation
- Increase bitcoin-knots memory limit to 4g, reduce dbcache to 2048
- Enable podman-restart.service in ISO for auto-start on boot
- Fix UI container Dockerfiles: ENTRYPOINT [], user root for rootless

App changes:
- Remove OnlyOffice (incompatible with rootless Podman)
- Replace with CryptPad reference (single-process, e2e encrypted)
- Fix NPM port mapping: 8181 → 81
- Fix OnlyOffice port mapping: 8044 → 9980 (now CryptPad: 3003)

AIUI & proxy:
- Add MODEL_MAP to claude-api-proxy (ISO + deploy)
- Map legacy model IDs (claude-haiku-4.5 → claude-haiku-4-5-20251001)

Kiosk:
- Move chromium-kiosk data dir to /var/lib/archipelago (data partition)
- Remove --metrics-recording-only (contradicted --disable-metrics)

Node bootstrapping:
- Add bootstrap-switchover.sh for live node updates
- ElectrumX UI improvements and nginx proxy fixes
- LND UI nginx config updates

Backend:
- Bitcoin health check uses .cookie auth (no plaintext creds)
- ElectrumX status endpoint improvements
- Network alias flag in install.rs for DNS reliability
