Add an option to automatically remove duplicates on queue and a drag and drop feature on queue

Problem Description

The title is exactly what it is. If you play next while playlist is shuffled that song would be lying around somewhere and repeat again by removing duplicates this makes sure only 1 stays in the queue and the drag and drip feature makes organizing queue mo easier cuz u can just long press and drop it somewhere instead of clicking move up or down one by one.

Proposed Solution

If u play next add the song below currently playing song and remove the duplicate somewhere.

Alternative Solutions

Instead of add and remove when u play next and there is duplicates the song would be instead moved below the currently playing song.

Additional Context

Start by tracing the queue and play-next flow, then inspect the queue UI and its existing move-up or move-down controls. Done means play-next leaves only one instance of the song in the queue and the queue supports long-press drag-and-drop reordering.
