feat: restructure sidebar hierarchy and add full audit view

Reorganize the sidebar into a proper hierarchy (Overview, Full Audit,
Namespaces) and add a Full Audit dashboard view that includes skipped
checks. Namespace routes move to /polaris/ns/:namespace to avoid
path collisions, and namespace detail pages now link out to the
Polaris dashboard.
