Jukebox TGUI update, Earphones autoplay, sound keys refactor (#21630)

V2 of [previous music playing
PR](https://github.com/Aurorastation/Aurora.3/pull/21466). TLDR no
longer uses the connect_range component for implementation because it
turned out a bit too inflexible for overlapping music players.

Removes a NanoUI template for the [TGUI
update](https://github.com/Aurorastation/Aurora.3/pull/21046).

New changelog:
  - refactor: "Ported Jukebox's NanoUI interface to TGUI."
- refactor: "Ported Jukebox audio playing functionality to a component."
- refactor: "Sound keys refactored from singletons to datums, along with
larger breakout of sound.dm to allow for easier SFX updates in future."
  - code_imp: "Expanded track datums to include track lengths."
- code_imp: "Reorganized music file folders for more intuitive access."
  - rscadd: "Earphone status feedback text now includes track length."
  - rscadd: "Added autoplay functionality to earphones."
- bugfix: "Fixed earphones' 'Previous Song' verb not sending you to the
end of the playlist when used while the first track is selected."
- bugfix: "Fixed gain adjustment for 'Konyang-1' (-23 dB -> standard
-9.8 dB)."
- bugfix: "Fixed y-offset of audioconsole-running overlay animation to
line up with the actual screen."
