[Feature Request]: Notification/sound when image fails to generate

[space-nuko]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

The notification feature is very useful if you tab out of the UI to do something else. However it will not trigger for failed gens. It would be nice to have peace of mind that webui will notify you in every case

Proposed workflow

1. Generate images that OOM
2. Webui plays a failed sound/notifies

Additional information

Maybe a separate sound for failed gens would be useful
