feat: German as the main language, English under /en, with a language switch

The site now exists in German (at the root, with /impressum and /datenschutz) and English (/en). A request without a language follows the visitor's choice from the language switch, then the browser language, then German; the old English legal addresses move to /en for good. All visible texts are data in src/content/de.ts and en.ts, so components hold none of their own. The header carries a DE/EN switch whose bit curtain covers the page while it is swapped and reopens at the same reading position. Title, description, canonical, hreflang, Open Graph, the share image, the sitemap and the structured data are per language. The privacy notice now describes the cookie that remembers the chosen language. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+/**
+ * Smart Proxy for Umami Analytics.
+ *
+ * This Route Handler receives tracking events from the browser,
+ * injects the secret UMAMI_WEBSITE_ID, and forwards them to the
+ * internal Umami API endpoint.
+ *
+ * This ensures:
+ * 1. The Website ID is NOT leaked to the client bundle.
+ * 2. The Umami API endpoint is hidden behind our domain.
+ * 3. We have full control over the tracking data.
