Rewrite frontend in Svelte

[Copilot]

Replaces the Next.js/React frontend with a SvelteKit + Svelte 5 (runes mode) application, maintaining full feature parity.

Stack changes

Before	After
Next.js 14 (App Router)	SvelteKit 2
React 18	Svelte 5 runes
TanStack Query + Context	Svelte stores + $state/$derived/$effect
TanStack React Table	Native sort logic
Headless UI	Custom Svelte dialog/popover components
react-leaflet	Leaflet (lazy-loaded, no SSR)
bun lockfile	npm

Key files

• src/lib/api.ts – API client (mirrors af.ts, fixes String → string types)
• src/lib/stores.ts – Auth state + sort field as writable stores
• src/lib/components/ – Header, Footer, LoginModal, VacancyGrid, VacancyCard, AreaPictures, FloorplanModal, Map
• src/routes/ – Three pages: /, /bostad/[id], /konto

Notable patterns

SSR load functions catch API errors gracefully (API may not be co-located during dev); auth is initialized client-side via onMount in the root layout. Map is dynamically imported to avoid SSR:

let LazyMap = $state<typeof import('$lib/components/Map.svelte').default | null>(null);

$effect(() => {
  if (showMap && browser && !LazyMap) {
    import('$lib/components/Map.svelte').then((mod) => { LazyMap = mod.default; });
  }
});

All original features preserved: vacancy grid with 6-field sorting, area photo gallery, floorplan modal, Leaflet map with geocoded markers, login/logout, auth-protected /konto, 30s auto-refresh, and urgency highlighting for deadlines <24h.
