fix: resolve tandoor, matrix, navidrome crash loops

- Tandoor: pin image to vabene1111/recipes:1.5.27 (latest tag pull
  failing with EOF from pull-through cache corruption)
- Matrix: update homeserver.yaml to use pg-cluster-rw.dbaas instead
  of legacy postgresql.dbaas service, update CNPG postgres password
- Navidrome: deleted corrupted SQLite DB (malformed disk image from
  proxmox-lvm migration), navidrome recreates fresh DB on startup
