What Happened
- The pull request replaces the dashboard's header-based UI with an AppShell/AppSidebar layout and introduces a new team settings path for review controls, moving key reviewer behavior options into dedicated sections. Reviewer settings such as trigger mode, draft-PR review, PR summaries, and autofix behavior (including severity threshold) are now persisted through the new `/dashboard/api/team-settings` flow.
