Delete a question from a quiz (ASK-119)

DELETE 
/quizzes/:quiz_id/questions/:question_id

Hard-delete one question from a quiz. The quiz_answer_options for the question CASCADE-delete; references from practice_session_questions.question_id and practice_answers.question_id are SET NULL so historical session data is preserved with a NULL question reference.

A quiz must always carry at least 1 question; an attempt to delete the last remaining question returns 400 with "quiz must have at least 1 question". The count check runs inside the same transaction as the delete so two concurrent deletes on a 2-question quiz can't both succeed.

Authorization: creator-only. The authenticated user must be quizzes.creator_id; any other authenticated user gets 403.

404 covers all of: quiz missing/soft-deleted, parent study guide soft-deleted, question missing, question belonging to a different quiz.

quizzes.updated_at is refreshed on every successful delete.
