Initial work on a queue sidebar panel

[greeeeeenbean]

Hi all,

I really wanted to have a way to see the queue and interact with it outside of the dropdown menu. I will be 100% honest, about half of this is ollama assisted, I'm not primarily a QT dev so this was mostly for my use. Feel free to decline :P

Here's a few screenshots:

Features include:

• It's a dockable widget, I played around with parenting it to the search window but I kind of like being able to move it... I still have that version if y'all want to see
• Skip directly to song in queue by double clicking or right click > skip (Unfortunately I couldn't figure out how to skip directly to the song and preserve the queue, so instead I skip N times to the selected song, preserving the queue.
• Setting to swap "Song Name - Artist Name" to "Artist Name - Song Name"
• Queue refreshes live when you switch songs

Edit... forgot to add I also added a live search feature requested in #243
