* fix(ui): make playlist toggle switches visible in all themes
The Public and Auto-import switches in the playlist list did not set a
color, so Material-UI used the theme's secondary color. Many themes use
secondary as a surface color close to the table background, which made
checked switches nearly invisible (Catppuccin, Rosé Pine, Monokai,
Moonbase and others).
Set color="primary" on the playlist switch, like every other switch in
the app, and make primary the default MuiSwitch color in useCurrentTheme
so future switches cannot regress. Fixes#6272.
* refactor(ui): drop secondary switch overrides from themes
Dracula, Gruvbox Dark, Tokyo Night and Tokyo Night Light styled checked
MuiSwitch colorSecondary to work around the same invisible-switch problem
(Gruvbox in #5064). With primary as the default switch color and every
switch in the app using it, no switch renders with colorSecondary anymore,
so these overrides are dead code.
Set document.body.style.backgroundColor to match the current theme's background
color whenever the theme changes. This fixes the white background that appeared
during pull-to-refresh gestures on mobile or overscroll on desktop, where the
browser reveals the area behind the app content.
The background color is determined by the theme's palette.background.default
value if defined, otherwise falls back to Material-UI defaults (#303030 for
dark themes, #fafafa for light themes).
