refactor(server): change asset update events to send IDs instead of full assets

- Change on_asset_update event to send asset IDs array instead of full AssetResponseDto
- Add asset.update event emission in asset service for update operations
- Update notification handlers to work with asset IDs
- Improve update logic to avoid duplicate events when metadata is updated
- Update frontend websocket types to match new event format
