style: auto-format with black + isort + prettier [skip ci-format-check]

- Change CreateAssetRequest.project_id from required to optional
- Auto-derive project_id from library.project_id when not provided
- Reorder validation: fetch library first, then derive project_id
- Add 4 unit tests covering all scenarios
- Fixes 422 error when frontend creates asset without project_id
