fix: restore missing AppTheme.Dialog.NoActionBar.MinWidth style

The style AppTheme.Dialog.NoActionBar.MinWidth was referenced by several
DialogFragment classes but was removed during cleanup, causing compilation errors:
- BaseDialogFragment.kt
- FeedbackFragment.kt
- RatingFragment.kt
- CollectionsFragment.kt

Restored the style definition with appropriate dialog theme properties.
