/// This utility function provides a consistent way to navigate to the video player

/// Parameters:
|

/// - [context]: The build context for navigation

/// - [metadata]: The Plex metadata for the content to play

/// - [preferredSubtitleTrack]: Optional subtitle track to select on playback start

|
/// - [preferredPlaybackRate]: Optional playback speed to set on playback start

/// - [selectedMediaIndex]: Optional media version index to use; if not provided,

|
/// loads the saved preference for the series/movie. Defaults to 0 if no preference exists.

/// useful for episode-to-episode navigation. Defaults to false.

///
|
|
/// Returns a Future that completes with a boolean indicating whether the content
