fix(ui): dynamic prompts not recalculating when deleting or updating a style preset

The root cause was the active style preset not being reset when it was deleted, or no longer present in the list of style presets.

- Add extra reducer to `stylePresetSlice` to reset the active preset if it is deleted or otherwise unavailable
- Update the dynamic prompts listener to trigger on delete/update/list of style presets
