fix: standalone on ubuntu (#865)

* Standalone on ubuntu

* fix: use port 3043 for Caddy, disable rooms, remove dead Caddyfile

- Caddy mapped to host port 3043 instead of 80/443 to avoid conflicts
- FEATURE_ROOMS=false in standalone web service
- Removed scripts/standalone/Caddyfile (dead code on this branch)
- Updated all URLs, port checks, docs to reference :3043
