This commit refactors the `PlayerViewModel` to simplify queue handling and remove unnecessary logging statements.

Key changes:
- **Simplified `updateCurrentPlaybackQueueFromPlayer`**: The logic for updating the current playback queue when shuffle mode is enabled has been removed. The queue now directly reflects the order from the `MediaController`'s timeline.
- **Removed redundant logging**: Several `Log.d` and `println` statements used for debugging have been removed from various functions, including `combine` for `favoriteSongs`, `updateCurrentPlaybackQueueFromPlayer`, `setupMediaControllerListeners`, `internalPlaySongs`, and `loadAndPlaySong`.
- **Improved `createShuffledQueue`**: Added a check for an empty songs list to prevent potential errors.

The previous shuffle implementation would only toggle the shuffle mode and then either pause the current song or start playing the first song in the library.

This change introduces a new `shuffleAllSongs` function in the `PlayerViewModel` that, when called:
1.  Enables shuffle mode on the media player.
2.  Selects a random song from the full list of songs.
3.  Starts playback with the random song and a shuffled queue of all songs.

The shuffle button in the library screen is updated to call this new function, providing the user with the expected shuffle behavior.

A unit test has been added to verify that the `shuffleAllSongs` function correctly calls the underlying `playSongs` method with a random starting song and the full song list.

Refactor library shuffle button functionality to play a random song when there are no songs playing / displayed, and generate a shuffled queue.

The album art in the Glance widget was being manually scaled to the exact dimensions of its container, ignoring the original aspect ratio. This caused the image to appear warped or stretched in non-square widget sizes.

This commit removes the manual `Bitmap.scale()` call and relies on the `Image` composable's `ContentScale.Crop` to handle scaling correctly. `ContentScale.Crop` ensures the aspect ratio is preserved while the image fills its bounds, preventing any distortion.

This commit removes an obsolete comment related to bitmap scaling in the `PixelPlayGlanceWidget.kt` file. The comment indicated that bitmap scaling was no longer handled in that specific code block, which is now the default behavior.

This commit introduces minor refactoring to the `PixelPlayGlanceWidget`.

Key changes:
- **Import Order:** The import statement for `androidx.glance.unit.ColorProvider` has been moved to align with standard import ordering.
- **Divider Color:** The `dividerColor` variable was removed and its `ColorProvider` value is now directly applied to the background modifier of a `Box` used as a divider. This simplifies the code by removing an intermediate variable.
- **Padding:** A comment indicating a fix for applying padding to an outer `Box` has been updated to reflect the change more accurately.
