- Add Traefik strip-prefix middleware so /t/{slug}/api -> /api on server
- Add priority to routers (server API=10, UI=5) to prevent conflicts
- Mount Docker socket + group_add in server containers for app deployment
- Add JAR storage, Docker network, volume env vars for runtime orchestrator
- Use HashMap for labels (>10 entries exceeds Map.of limit)
