feat: Scorecard im Instagram 4:5 Hochformat (1080×1350) — Title + Score + Matrix prominenter

User-Frage: 'Mach die Scorecard im Instagram-Format hochkant. Was genau
ist das nochmal? Vier zu fünf?' — Ja, 1080×1350 ist das Instagram-Feed-
Format mit dem groessten vertikalen Real-Estate. Stories sind 9:16,
quadratisch ist 1:1.

Neuer format=portrait (1080×1350) in /v2/scorecard und
/api/assessment/scorecard.png. Layout speziell vertikal:

- Title gross (32 pt) mit reichlich Leading
- Fraktions-Pills in eigener Zeile
- Score-Row: HUGE Zahl (110 pt) links + Empfehlung-Wort rechts,
  oben/unten zarte Trennlinien — klare Bewertungs-Anker
- Matrix 5×5 gross (380×380) mit Legende daneben — User sieht
  sofort welche Felder + - + - sind
- gwoe_begruendung als 5-zeilige Zusammenfassung darunter
- Footer am Boden

Instagram-Button im Share-Block stellt von square auf portrait um.
