Migrate all page components from the @cameleer/design-system v0.0.3
example UI, replacing mock data with real backend API hooks. This brings
richer visuals (KpiStrip, GroupCard, RouteFlow, ProcessorTimeline,
DateRangePicker, expandable rows) while preserving all existing API
integration, auth, and routing infrastructure.
Pages migrated: Dashboard, RoutesMetrics, RouteDetail, ExchangeDetail,
AgentHealth, AgentInstance, OidcConfig, AuditLog, RBAC (Users/Groups/Roles).
Also enhanced LayoutShell CommandPalette with real search data from catalog.

Add AdminLayout wrapper with Tabs component for navigating between
admin sections: User Management, Audit Log, OIDC, Database, OpenSearch.
Nest all /admin/* routes under AdminLayout using React Router's
Outlet pattern so the tab bar persists across admin page navigation.
