Convert Flask routes to FastAPI in anime controller

- Convert Flask Blueprint to FastAPI router
- Replace @app.route() with FastAPI route decorators (@router.get, @router.post)
- Update route parameter syntax from <int:id> to {id: int} format
- Convert Flask request object usage to FastAPI Query/Depends parameters
- Update response handling to return dicts instead of Flask jsonify()
- Integrate SeriesApp as business logic layer for anime operations
- Add anime list, search, and rescan endpoints using SeriesApp
- Include anime router in main FastAPI application
- Mark route conversion tasks as completed in web_todo.md
