style: fix lint warnings and a11y issues

- Add proper for/id associations for color picker labels (ConfigSidebar)
- Add tabindex and svelte-ignore for dialog overlays (GitPanel)
- Add standard mask/line-clamp CSS properties for compatibility
- Remove unused .stat-highlight CSS selector (StatsDisplay)
- Fix SvelteSet reactivity by using .clear() instead of reassignment
- Make updateNotification properly reactive with $state
