F3: authenticated unknown routes now redirect to /dashboard instead of
rendering private NotFound.
F2: Header shows a warning Chip with the current onboarding next_step
when the user has not completed onboarding (next_step != 'ready').
Chip navigates to /dashboard on click. Hidden on xs screens.

Removed NeoUserContext and NeoInstituteContext from the gateway
spinner. They were blocking ALL authenticated routes until Neo4j
graph data was loaded, which took 1-8 seconds and caused persistent
spinners. Now only UserContext (Supabase profile, ~200ms) must be
ready before routes render. Each page handles its own graph data
loading state independently.
