feat: edit and delete pairs in GenerateIt

- Backend: PATCH /api/directus/db-pairs/<id> updates level, statement, question
  (creates question if new, removes if cleared)
- Backend: DELETE /api/directus/db-pairs/<id> removes pair + all junctions,
  questions and statements
- Frontend: inline edit form per pair (level slider, statement, question)
- Frontend: delete button per pair with confirm dialog
- api.ts: updateDbPair, deleteDbPair
