feat: persönlichere Profilseite + iOS-App-Setup

Profil: Begrüßung in Zielsprache, Kategorie-Punkte-Übersicht,
ruhigerer Header (kein rotierender Avatar/Online-Dot), Notch-Fix
und kompaktere Aktivitäts-Heatmap. Außerdem Capacitor-iOS-Projekt
und diverse Auth/Feed/Audio-Verbesserungen aus dem Premium-Redesign.
