feat(note-list): add option to disable swipe actions

Add a toggle in the "Appearance and behavior" settings to enable or
disable swipe gestures (delete and favorite) in the note list.

The default value is set to enabled, preserving existing behavior while
allowing users who accidentally trigger these actions to disable them.

Changes:
- Add `swipe_actions` preference to `preferences.xml`
- Add `isSwipeEnabled` global state in `NotesApplication`
- Update `NotesListViewItemTouchHelper` to respect the setting
- Create `ic_swipe_grey600_24dp.xml` for the settings icon
