improve health checks across all nomad job specs

- traefik: TCP → HTTP check on /ping (enable ping entrypoint)
- gitea: check path → /api/healthz
- jellyfin: TCP → HTTP check on /health
- glance: TCP → HTTP check on /
- sonarr/prowlarr: check path / → /ping (×2 checks each)
- ntfy/transfer/deluge/openreader/authelia/pgadmin: add name and port to existing checks
- postgres: remove invalid TCP check (Connect-enabled service)
- unifi: TCP → script check via curl (macvlan host isolation workaround)
