feat: add AI draft endpoint for learning sheets with server-side checks
POST /api/learning/sets/ai-draft (LearningManage + AiUse) builds a fixed system prompt from validated parameters, validates every returned task, recomputes number solutions and stores the result as an unassigned draft with provenance. AiStatusDto reports whether the generation provider is a cloud provider. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
