feat: implement missing shop-specific Qdrant API endpoints

Adds comprehensive shop-specific endpoints to resolve frontend 404 errors:

• /api/qdrant/shops/:shopId - Get shop Qdrant info and statistics
• /api/qdrant/shops/:shopId/embeddings - List all shop embeddings
• /api/qdrant/shops/:shopId/errors - List shop-specific Qdrant errors
• /api/qdrant/cleanup - Trigger manual Qdrant cleanup process
• /api/qdrant/shops/:shopId/schedule-deletion - Schedule shop data deletion

Each endpoint includes:
- Proper authentication and authorization
- Shop validation and error handling
- Consistent response format with success/data structure
- OpenAPI documentation with parameters and responses

Resolves frontend-backend API contract mismatches causing 404 errors
on production server. All endpoints tested and fully functional.
