Implement story integration backend services:
- Create StoryService (Application/Services/StoryService.cs) with full CRUD operations
- Create StoryGenerationService (Application/Services/StoryGenerationService.cs) for AI-powered story generation
- Uses IMistralService for text generation
- Uses ITtsService for audio generation
- Splits stories into segments per lesson
- Create StoryUnlockService (Application/Services/StoryUnlockService.cs) for progress management
- Handles lesson completion → story segment unlocking
- Create StoryController (Presentation/Controllers/StoryController.cs) with 12 endpoints:
- GET /api/story/levels - list levels with stories
- GET /api/story/levels/{levelId}/segments - get segments for level
- GET /api/story/segments/{id} - get specific segment
- POST /api/story/segments - create segment (Admin)
- PUT /api/story/segments/{id} - update segment (Admin)
- DELETE /api/story/segments/{id} - delete segment (Admin)
- POST /api/story/levels/{levelId}/generate - generate story with AI (Admin)
- POST /api/story/segments/{segmentId}/audio - generate audio (Admin)
- GET /api/story/levels/{levelId}/progress - get user progress
- POST /api/story/segments/{segmentId}/complete - mark as completed
- GET /api/story/levels/{levelId}/next - get next segment
- GET /api/story/segments/{segmentId}/unlocked - check if unlocked
- GET /api/story/segments/{segmentId}/audio - get audio URL
- GET /api/story/levels/{levelId}/lessons-with-stories - get lessons with story status
- Register all services in Program.cs DI container
