Erich Blume ca0c9354ee Add borgmatic backups for authentik and immich databases (#314)
## Summary

- Add `authentik` database (blumeops-pg cluster) to borgmatic pg_dump backups
- Add `immich` database (immich-pg cluster) to borgmatic pg_dump backups
- For immich-pg: new borgmatic managed role with `pg_read_all_data`, ExternalSecret, Tailscale LoadBalancer service, and Caddy L4 TCP proxy on port 5433
- Update backup docs to reflect all four CNPG databases + mealie SQLite

## Deploy plan

Deploy order matters — k8s resources must exist before ansible can route to them:

1. **ArgoCD (databases app):** sync to pick up immich-pg borgmatic role, ExternalSecret, and Tailscale service
   ```
   argocd app set blumeops-pg --revision feature/borgmatic-all-pg-backups
   argocd app sync blumeops-pg
   ```
2. **Wait** for `immich-pg-tailscale` service to get a Tailscale IP and `immich-pg.tail8d86e.ts.net` to resolve
3. **Ansible (caddy):** deploy Caddy L4 route for port 5433
   ```
   mise run provision-indri -- --tags caddy
   ```
4. **Ansible (borgmatic):** deploy updated config and .pgpass
   ```
   mise run provision-indri -- --tags borgmatic
   ```
5. **Verify:** trigger a manual borgmatic run and check all four pg_dump streams succeed
   ```
   borgmatic --verbosity 1 2>&1 | grep -E '(Dumping|ERROR)'
   ```

## Test plan

- [x] `kubectl kustomize` builds cleanly
- [x] `ansible --check --diff` for borgmatic and caddy show expected changes
- [ ] ArgoCD sync succeeds for databases app
- [ ] `immich-pg.tail8d86e.ts.net` resolves
- [ ] `pg.ops.eblu.me:5433` accepts connections
- [ ] `borgmatic --verbosity 1` dumps all four databases without errors
