fix(qt): drop custom style plugin, use Fusion + qt6ct custom palette

The cyberqueer style plugin only overrode polish(QPalette&) with colors
identical to those already in cyberqueer.conf. Qt failed to load the
plugin for apps after the first, falling back to Fusion Light entirely.
Switching to the built-in Fusion style with qt6ct's custom_palette
mechanism gives the same result reliably for every app.
