Section deep-links: /?app=settings#ai-options now switches the Settings
ListView to the KI tab and scrolls to the ai-options anchor. ListView
reads the URL hash on mount and maps it to a category via the existing
searchIndex anchors. The AI-tier dropdown "KI-Einstellungen" link now
targets /?app=settings#ai-options instead of just /?app=settings.
Profile & Themes workbench consolidation — same pattern as Settings:
- Delete standalone /profile and /themes routes (redundant with the
workbench apps registered in app-registry)
- Migrate all links: PillNavigation profileHref/themesHref, dashboard
QuickActionsWidget, +layout theme-switcher "Alle Themes", and the
scene context-menu "Hintergrund ändern"
Credits stays as a standalone route — no workbench app registered for it.
