feat: add plugin/theme disable gates and move policy controls to their admin pages
- Add `pluginsEnabled` and `themesEnabled` master feature gates to FeatureGates - Move theme policy UI (default theme, built-in/admin theme toggles, user uploads toggle) from policy page to themes admin page - Add plugin policy UI (plugins enabled toggle) to plugins admin page - Remove theme policy section and plugin/theme gates from policy page (with note directing to respective pages) - Hide Themes and Plugins settings tabs when their feature gate is disabled - Fix dark mode visibility of all admin toggle switches (bg-white → bg-background, increase off-state track opacity)
