feat(phase-c): Vite + Svelte 5 Infrastruktur + erste 2 Panels migriert

- frontend/ eingerichtet: Vite 6, Svelte 5 (Runes), TypeScript
- Stores: status/jobs/system mit $state-Runes (status.svelte.ts etc.)
- main.ts ersetzt main.js: bundelt Legacy-Panels (overview/models/server/
  jobs/cookbook/connect) + mountet neue Svelte-Panels (guides/news)
- GuidesPanel.svelte: statischer Guide mit Akkordeon-Tutorials + Konzept-Grid
- NewsPanel.svelte: reaktives Newsboard mit API-Fetch + Upgrade-Vorschlaegen
- Vite-Output: static/dist/main.js (committet, kein Build auf dem Server)
- index.html: laedt jetzt static/dist/main.js statt static/js/main.js
- Build: 118 Module → 134 kB (gzip: 44 kB)

Naechste Schritte: Overview → Jobs → Server → Models → Cookbook migrieren.
