feat(ui): Settings-Modal auf Sidebar-Kategorien umbauen

TabControl bleibt Content-Host, TabStrip wird retempliert (nur
PART_SelectedContentHost) und durch eine zweigruppige Sidebar
(BASIS/ERWEITERT) ersetzt. General wird in Allgemein/Ausfuehrung/Berichte
gesplittet, Session Skills (Checkbox-Liste aus General + Skills-Tab)
zu einer Liste zusammengelegt, und ein Repo-Hinweisstreifen erscheint
auf Worktrees/Prime Claude/Session Skills/Berichte solange keine Liste
ein WorkingDir hat. Fensterbreite 580 -> 700.
