- selectQuestions: shuffle final result for random question order
- grader: wrap LLM invoke in try-catch, default score 5 on failure
- grader: inner try-catch for JSON parse errors, graceful fallback
selectQuestions now only checks item-level PUBLISHED status.
startSession already handles bank detection by counting published items.
This fixes assessment always falling back to LLM generation.

- remove: forbid PUBLISHED bank deletion
- removeItem: forbid PUBLISHED item deletion
- generateQuestions: restrict to DRAFT status only
- frontend: render MULTIPLE_CHOICE options/judgment/followupHints
- frontend: add judgment and followupHints to QuestionBankItem type
