Permission Handling

[alperozturk96]

1. After the first rejection, the storage permission request dialog does not appear again.
2. There is no need to use the (permissionRequired: Boolean = false) parameter because if the user lacks permission, we must request it again regardless.
3. An internal boolean flag (isStoragePermissionRequested) is unnecessary for determining whether to request storage permission.
4. A custom DialogFragment for requesting permission is not required.

If shouldShowRequestPermissionRationale returns true, display the native alert dialog (no need for StoragePermissionDialogFragment). Otherwise, show a Snackbar with an action to open the settings.
