feat(flyer-import): add session management and retrieval endpoints

- Add new API endpoints for retrieving flyer import sessions: - GET /flyer-import/sessions/latest - Retrieve latest session for user - GET /flyer-import/sessions/:sessionId - Retrieve specific session - Implement session persistence and restoration in Flutter UI - Add toJson() methods to FlyerImportItem and FlyerImportResult for serialization - Add new FlyerImportSession domain model for local session management - Add unit test file for FlyerImportService - Update FlyerImportController with new endpoints and user ID extraction - Update FlyerImportService with session retrieval logic and response mapping - Update API paths in Flutter client - Add session restoration on widget init in FlyerImportTab
