refactor: convert settings page to separate view panels

- Replace scroll-based navigation with view switching
- Add useSettingsView hook for managing active panel state
- Extract Audio section into its own component
- Remove scroll-mt-6 classes and IDs from section components
- Update navigation config to reflect current sections
- Create barrel export for settings-view hooks

This improves performance by only rendering the active section
instead of all sections in a single scrollable container.
