feat: Social-Bild erweitert (Logo, Status-Pill, Description, Story, Themes) + OG-Route + Calendar-Buttons aufgeräumt

Social-Bild-Endpoint:
- Logo aus page_config (gefärbt in Theme-Akzent) statt Wordmark
- Status-Pill (ONLINE/Demo/Info/Anhörung/Stammtisch/Sitzung) aus
  Titel-Keywords und Tags, mit eigener Farbe
- Description-Snippet unter Titel (Square + Story)
- Story-Format 1080x1920 ergänzt
- Theme-Varianten: wald (default), transparent-onlight,
  transparent-ondark
- Uhrzeit unter Datum (2. Zeile) mit Clock-Icon im Akzent-Grün
- QR linksbündig bei Square + Story, kleiner (180px)
- Location-Pin top-aligned, Title-Fontsize dynamisch bei langen Titeln

Neue Route /termin/[slug]: OG-Meta-Tags für Link-Previews
(FB/WhatsApp/Twitter), JS-Redirect zu /kalender/#event-<slug>.
QR-Code im Social-Bild zeigt jetzt auf /termin/[slug].

Calendar-Block Aktionen reorganisiert:
- Primary-Reihe: Mehr Info, Auf Karte, Anhang
- Kompakte Toolbar (gerahmt): Kalender (ICS, Google) | Teilen (Link,
  Share, Bild) | Im Grid
- Theme-Selector im Social-Modal mit Vorschau-Hintergrund-Indikator
