nixos/stalwart-mail: rocksdb as default storage 

This sets RocksDB as the default storage backend for `stateVersion` >=
24.11. For previous `stateVersion`s, the structured data and blobs
remain on SQLite and the filesystem respectively.

This is closer to the suggested upstream configuration for fully local
storage.

- The `stalwart-mail` module now uses RocksDB as the default storage backend

  for `stateVersion` ≥ 24.11. (It was previously using SQLite for structured

  data and the filesystem for blobs).
