Make album art zoom and color scheme configurable

Browse Source 
Zoom level is a dropdown (Off/Subtle/Moderate/Strong) controlling how far
the album art zooms in during its breathing effect; Off skips the
animation.Transformation entirely and just shows a static crop.

Color schemes now match SUB/WAVE's own web UI theme picker (Blueprint,
Classic Dark, Classic Light, Cyberpunk, Flare, Recon, Signal, Vinyl) so a
station can mirror its own site theme on the device, including a
background fill that was previously hardcoded to black.
