fix: update types-grpcio dependency version and improve meeting filtering

- Changed the types-grpcio dependency from `>=1.0.0.20251009` to `==1.0.0.20251001` in `pyproject.toml` and `uv.lock` for consistency.
- Enhanced the meeting filtering logic in the `MeetingStore` and related classes to support filtering by multiple project IDs, improving query flexibility.
- Updated the gRPC proto definitions to include a new `project_ids` field for the `ListMeetingsRequest` message, allowing for more granular project filtering.
- Adjusted related repository and mixin classes to accommodate the new filtering capabilities.
