…copy/move dialog).

* The issue occurred because the logic for opening ZIM files was inside the KiwixReaderFragment, and if the user was on any other screen while using the application, this code was not triggered. As a result, the copy/move dialog was not shown. To resolve this, we moved the functionality to the KiwixMainActivity.

* When opening the ZIM file via file picker or deep linking, we were obtaining the file path using the getZimFileFromUri() method to perform the renaming for the move functionality. However, on Android 14 tablets, the URI was not resolved correctly by this method, leading to a "ZIM file not found" error.
* To fix this issue, we removed the dependency on the `getZimFileFromUri()` method in the Play Store variant, as future Android versions may handle URIs differently. We refactored our code so that the copy/move functionality works independently of this method and now works directly with Android's provided URI.

* Improved the test case to remove the file from the emulator to free up device storage, as we do not have access to this file after running the test case, and it will remain in storage.
