Daniel f2d15c3c57 Junction table for shared questions; verification blocking; semantic bank search; bug fixes
Question sharing (edits now propagate):
- quiz_question_links junction table: quizzes reference questions, not own copies
- Existing questions migrated to junction (idempotent ON CONFLICT DO NOTHING)
- from-bank and from-category create quiz by adding junction links (no copying)
- Editing a question via QuizEditPage or bank Edit modal updates the ONE record
  visible in all quizzes that reference it
- Delete from quiz: only deletes Question record if no other quiz references it
- quiz_service: fixed position counter (was using len() incorrectly, now enumerate)
- question.quiz_id renamed to source_quiz_id in Python (DB column still quiz_id)
- All attempts/quizzes/search code updated to use junction helper or source_quiz_id

Bug fixes:
- PostgreSQL en_US.utf8 collation B-tree index corruption on users.email
  Fixed by ALTERing column to COLLATE "C" in migration + immediate repair
- get_current_user now blocks unverified users on ALL endpoints (403 + X-Unverified header)
  api/client.js intercepts X-Unverified=true and auto-logs out to /login
- Search (quiz + bank): correct_answer and explanation now included in matching_questions
  so study modals work correctly
- Keyword search: order_by updated to use source_quiz_id
- Bulk category: changed from PATCH with body array to POST with Pydantic body
  (fixes null category_id removal)
- Question bank: edit button added, answer highlighting removed from list view
- QuestionBankPage: Keyword/Semantic/Hybrid search toggle
- Login: login error message stays visible (removed immediate reload)
