QC approval now transitions jobs directly to pending_final_review
since translation, TTS, and accessible video rendering happen before
QC review. Removes unnecessary translate_and_synthesize_task trigger
on approval.
- Update approve_source() to use PENDING_FINAL_REVIEW status
- Update bulk_approve_jobs() to use PENDING_FINAL_REVIEW status
- Remove translate_and_synthesize_task.delay() calls from both endpoints
- Update JobDetail progress indicator to reflect new flow
- Update CLAUDE.md state machine documentation
