feat: major infrastructure improvements
Reliability:
- Add swap role (2GB, swappiness=10, idempotent via /etc/fstab)
- Add mem_limit to plane-worker (512m) and plane-beat (256m)
- Add health checks to all services (traefik, vaultwarden, forgejo,
  plane-*, syncthing, prometheus, grafana, loki)

Code quality:
- Remove Traefik Docker labels (file provider used, labels were dead code)
- Add comment explaining file provider architecture

Observability:
- Add AlertManager with Telegram notifications
- Add Prometheus alert rules: CPU, RAM, disk, swap, container health
- Add Loki + Promtail for centralized log aggregation
- Add Loki datasource to Grafana
- Enable Traefik /ping endpoint for health checks

Backups:
- Add backup role: pg_dump for forgejo + plane DBs, tar for
  vaultwarden and forgejo data
- 7-day retention, daily cron at 03:00
- Backup script at /usr/local/bin/backup-services
