Feature/background music

[priyanshirai231-spec]

Description

Added a background music mixing feature that allows creators to upload an audio track and mix it with the original video audio. The feature includes controls for adjusting the original video volume, balancing background music volume, and optionally looping the background track to match the video duration using FFmpeg's amix filter graph configuration.
