feat: v1.16.0 — 15 New Themes, W98 Overhaul, Aqua Quartz Polish

New themes: Aqua Quartz (Mac OS X Aqua, skeuomorphic), Spider-Tech,
T-800, B-Runner, Hill Valley 85, TetraStack, Turtle Power, Insta,
ReadIt, The Book (new Social Media group), W3.1, Jayfin (Jellyfin).

W98 rebuilt from scratch: authentic #d4d0c8 warm-gray, full 4-layer
3D bevel on all panels/buttons (raised/sunken on press), title bar
gradient on song name, navy progress fill, 16px styled scrollbar.

Aqua Quartz: all button variants now jelly-styled, blue Source List
sidebar with white pill nav, aluminium pinstripe background.

Theme Picker: groups and themes sorted alphabetically, Mediaplayer
group renamed, Pandora/Order of the Phoenix/Imperial Sith removed.

Fix: AlbumDetail genre propagation, W98 accordion active state,
Aqua Quartz sidebar labels, W98 connection indicator contrast.
