feat: Replace theme dialog with segmented buttons

Browse source 
Replaces the dialog pop-up for theme selection (Light, Dark, System)
with `SegmentedButton` widgets in the theme settings page.

The new UI uses:
- Light theme option on the left.
- System theme option in the middle.
- Dark theme option on the right.
- A checkmark icon (`Icons.check`) for the selected theme.
- Respective icons (`Icons.light_mode`, `Icons.auto_awesome`, `Icons.dark_mode`)
  for unselected themes.

The `ModeSelectionDialog` has been removed as it's no longer necessary.

Note: Full UI and persistence testing could not be completed due to
sandbox limitations where the Flutter SDK was not available.
The core code implementation was verified.
