refactor(filters): replace is_fully_proofread with proofread_status in ReviewFilters

Description:

This R updates the frontend review-filter flow to match the backend proofread status changes.

The backend replaced the old boolean field is_fully_proofread with a new enum field called proofread_status, which supports:

• no - proofreading has not started
• partial - proofreading is in progress
• yes - proofreading is completed

Frontend changes made:

• Updated ReviewFilters in useToolEventFilters.ts to support proofread_status instead of is_fully_proofread.
• Updated event-filter normalization and sanitization so backend-provided proofread_status values are preserved.
• Removed the old is_fully_proofread: false fallback from Document Digitization.
• Document Digitization now sends only media_type: ['document'] by default.
• This allows the backend /records/for-review endpoint to apply its own proofread priority order:
  1. partial
  2. no
  3. yes
• Added a regression test to ensure the removed is_fully_proofread field is no longer sent from the Document Digitization review request.
