fix: add rendering_video status to MongoDB schema validator

The rendering_video status was defined in job.py and frontend types but
was missing from the MongoDB schema validator, causing document update
failures when jobs transitioned to the rendering_video state.

Changes:
- Add migration script to update existing databases
- Update mongodb-init.js for new database setups
