fix: use self-portaling DetailPanel from design system v0.1.5

DetailPanel now portals itself to #cameleer-detail-panel-root (a div
AppShell places as a sibling of .main in the top-level flex row).
Pages just render <DetailPanel> inline — no manual createPortal,
no context, no prop drilling.

Remove the old #detail-panel-portal div from LayoutShell and the
createPortal wrappers from Dashboard and AgentHealth.
