v2.5 — Context-aware Portraits + DE→EN Translation

- Chat-Kontext wird in Portrait-Prompt einbezogen:
  - Outfit-Änderungen ('umgezogen', 'Kleid', 'Hoodie' etc.)
  - Posen ('lacht', 'schläft', 'sitzt' etc.)
  - Szenen ('Café', 'Schlafzimmer', 'Nacht' etc.)
- I2I denoise steigt auf 0.55 bei Outfit-Wechsel (Gesicht bleibt, Kleidung ändert sich)
- Deutsche Appearance-Felder → englische Model-Tags (translate_map)
- SDXL-Auflösung 1024x1024 (war 512 — produzierte Chaos)
- 'upper body' statt 'headshot' (war nur Scheitel)
