nixos/stalwart: switch logging from stdout to journal 

journald's centralized logging has many advantages:
- External centralized logging can simply source from journald
- journald's auto-vacuum options (e.g. SystemMaxUse) can make sure logs
  don't take up too much space
- Logs are in a single timeline, which is useful for analysis

  - `systemd.services.stalwart` owned by `stalwart:stalwart`. The `user` and `group` are configurable via `services.stalwart.user` and `services.stalwart.group`, respectively. By default, if `stateVersion` is older than `26.05`, will fallback to legacy value of `stalwart-mail` for both `user` and `group`.

  - Default value for `services.stalwart.dataDir` has changed to `/var/lib/stalwart`. If `stateVersion` is older than `26.05`, will fallback to legacy value of `/var/lib/stalwart-mail`.

  - Default tracer name and type have changed to `journal`. If `stateVersion` is older than `26.05`, will fallback to legacy value of `stdout`.



- `services.eintopf` has been renamed to `services.lauti` to align with upstream re-brand as a community online calendar.
