Andrew Charlwood 7d51efc25e feat: add two-view architecture with sidebar navigation (Task 10.2)
- Add active_view and selected_comparison_directorate to app-state
- Sidebar: rename to Patient Pathways + add Trust Comparison nav item
- View container pattern: two view divs toggled by active_view
- Navigation callback: sidebar clicks switch views + update active state
- Trust Comparison placeholder landing page with tc-landing structure
