Rework SettingsView into a tabbed, card-based layout with improved controls and UX. Adds save status indicators/animations, a back navigation button (useNavigate), badges, separators, and consistent Button/Input/Card/Tabs components. Refactors CATEGORY_ICONS to use React.ElementType and updates icon imports (BookOpen, ImageIcon, etc.). Introduces a new Slider component (src/components/ui/slider.tsx) and replaces the old range input for grid item size with the new Slider. Also consolidates custom color inputs, favicon upload UI, language selection, and other display/content controls into structured cards for clarity.
