- Fix a bug where deleting a local model when there are >1 local models shows the wrong download status.

- Don't go back to model selection screen automatically when there is an error during model initialization, so that users have a chance to change model parameters (e.g. accelerator) to retry the initialization.
- Show error dialog properly in prompt lab screen.
