- Completely reverted quiz_tasks.py to simple standard extraction with chunking
(no more two-phase detection that broke PREP 2012/2014)
- OCR normalization kept: 'Pref erred'→'Preferred', 'ltem'→'Item'
- The extraction prompt already handles both 'Correct Answer: X' and
'Preferred Response: X' inline formats — no special detection needed
- PREP 2013 (separate answer key) will be implemented as a separate option
user selects at extraction time, not automatic detection
Also in this commit:
- Fixed quiz delete 500 error (source_quiz_id attribute name)
- Added trash bin (soft delete, restore, permanent delete)
- Added hide/publish toggle per quiz (moderators see all, users see published only)
- Quiz progress saved to Redis — survives logout, works cross-browser
- Resume in-progress quiz from any browser
- ConfirmButton component replaces all window.confirm/prompt
- Delete own attempts endpoint
- TrashPage, AdminPage trash/jobs links in Settings
