feat: add status field to themes collection and update migration scripts

- Added a new "status" field to the themes collection with options: draft, published, and rejected.
- Updated the migration script to include the new field and its options.
- Created a new ingestion migration script to ensure the "status" field includes "rejected" as an option if not already present.
- Added multiple hot-update files for webpack to support the new changes in the frontend.
