Add borgmatic backup for Mealie SQLite, set image tag

- Add before_backup hook to borgmatic: kubectl exec + python3 sqlite3
  .backup to safely dump the database, then kubectl cp to host
- Include k8s-dumps directory in borgmatic source_directories
- Generic pattern: borgmatic_k8s_sqlite_dumps list in defaults
- Fix PVC storageClassName: standard (not local-path) on minikube
- Set container image tag to v3.12.0-5c5fd18 from CI build
