Rebrand: Google Opal AI / DeepMind -> Aura Studio (drop impersonation)

Renamed the product across index.html + app.js + manifest.json + sw.js: Google Opal AI -> Aura
Studio, Google DeepMind -> Aura AI, Opal Mini-Apps -> Aura Mini-Apps, Gemini 2.0 -> Gemini 3.5.
Kept accurate tech attribution (Google Veo/Gemini). Internal identifiers (localStorage keys, SW
cache) unchanged except a version bump to force PWA refresh (aura-studio-v9, sw.js?v=9).
