The FloatingActionButton remains hidden after returning to Home from drawer category views

Describe the bug
The FloatingActionButton (FAB) is correctly hidden in drawer category views where file creation is not supported. However, after leaving one of these views and returning to Home using the Home button, the FAB remains hidden in the normal filesystem view. The FAB only reappears after an additional back navigation.

To Reproduce

1. Launch Amaze
2. Navigate to a drawer category view (for example: Documents, Images, APKs, or Trash Bin)
3. Observe that the FAB is hidden (expected behavior)
4. Tap the Home button
5. Observe that the FAB is still hidden
6. Open a normal filesystem directory from Home
7. Observe that the FAB remains hidden in the directory view
8. Tap Back
9. Observe that the FAB returns

Expected behavior
The FAB should remain hidden in drawer category views, but it should be restored immediately when returning to Home or a normal filesystem directory via the Home button.

Actual behavior
After leaving a drawer category view and returning to Home, the FAB remains hidden in normal filesystem directory views where file creation should be available. The FAB only returns after an additional back navigation.

Additional context

• The FAB is hidden as expected in drawer category views.
• The issue occurs when returning from a drawer category view to Home using the Home button.
• The problem appears to be related to FAB visibility not being restored when transitioning back to a normal filesystem view.

Reproduce the navigation from a drawer category view to Home, then into a normal filesystem directory, and trace where FloatingActionButton visibility is updated during those transitions. Confirm the FAB is hidden in category views and restored immediately on Home and normal directory views, without requiring an extra Back action.
