refactor: Avatar-Editor als wiederverwendbares Modal-Modul

- Neues avatar-editor.js: Upload, Paste, AI-Generate, Scale, Clear in einem Modal
- Session + Agent Pages: ~280 Zeilen doppelter Avatar-Code → je 5 Zeilen AvatarEditor.init/destroy
- Avatar-Preview klickbar → öffnet Modal mit allen Einstellungen
- chat.css: Shared-Content Message-Styling (max-width, border)
