feat(lora-pool): add external value handling and config update support

- Add `onSetValue` callback to handle external updates like workflow loading
- Implement `updateConfig` method for direct widget value updates
- Add value change detection in `restoreFromConfig` to prevent unnecessary updates
- Remove debug console log on component mount
- Extend widget value type to support legacy config format
