Add a “Stop” button to explicitly stop active playback streams

Please consider adding a dedicated “Stop” button to the player controls to allow users to explicitly stop the current playback stream.

Currently, when the application is closed while music is still playing, the server-side playback session can not be properly terminated. The stream continues running on the Jellyfin server. As a result, the Playback Reporting plugin continues recording playback time, causing the reported play duration to be significantly longer than the actual listening time.

A “Stop” button would allow users to manually terminate the playback session before closing the application, ensuring that the Jellyfin server correctly stops the stream.

Thank you for considering this improvement.
