Fixed: When a note is deleted, the corresponding file remained in sto…

…rage.

* The note file is now deleted from storage when the user selects multiple notes and deletes them from the "Notes" screen.
* Improved note deletion in the "Note Dialog." Previously, when deleting a note from the `AddNoteDialog` on the Notes screen, the file was removed from storage, but its entry remained in the database, causing the note to still appear on the "Notes" screen after deletion. This issue has now been fixed.
