refactor: Gott-Datei settings_modal.dart in 12 Dateien aufgeteilt

Reine Verschiebung per Dart part/part-of (keine Umbenennung, keine Logikänderung) - settings_modal.dart schrumpft von 5541 auf 270 Zeilen. Verifiziert per automatisiertem Blockvergleich gegen das Original und flutter analyze (Baseline unverändert: 1 bekannter Hinweis). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
