fix: show uploaded images inline instead of just the filename

Browse source 
Bilder wurden bisher nur als Textzeile "Hochgeladen: X" bestätigt, nie
tatsächlich angezeigt. Zeigt jetzt sofort beim Auswählen eine lokale
Vorschau im Transkript (data:-URL, passt bereits in die bestehende
img-src-CSP), bevor der Upload überhaupt beim Server ankommt.

Verifiziert per echtem Playwright-Browsertest inkl. fake mic/WebRTC:
Bild landet als <img> im Transkript, keine Konsolenfehler.
