Implemented native Picture-in-Picture (PiP) mode for Android by updating the AndroidManifest, MainActivity, and introducing PipService and VideoPIPManager. Updated video player screen and controls to support toggling PiP mode, and added localized strings for the PiP button in multiple languages.
Relating to Issue #44: At this time PiP in Plezy only supports Android devices... iOS+MacOS will require significant changes to the video player for it to work properly...
