Round 10: Add Traefik routing to monitoring services

- Added Traefik labels and routing to prometheus, grafana, loki, cadvisor
- Fixed Grafana ROOT_URL to use domain-based URL (https://grafana.${DOMAIN})
- Added uptime-kuma bypass rule in Authelia (needs initial setup)
- Updated all services to use traefik-network
- Synced domain from kelin-hass to kelin-casa across all configs
- Fixed missing tls=true label on uptime-kuma
- Note: Loki is API-only service (no web UI, accessed via Grafana)
