Add an option in AnkiMobile for users to choose where the flag button appears on the review screen, such as the top-left or top-right corner.
Current Behavior
AnkiMobile currently places the flag button in the top-left corner, whereas Anki Desktop and AnkiDroid place it in the top-right corner.
Proposed Solution
Introduce a setting that allows users to select the flag button’s position, with options such as:
* Top Left
* Top Right
Default behavior: Preferably, place the flag button in the top-right corner to match Anki Desktop and AnkiDroid.
