Rewire the setup wizard UI to the persistent session endpoints:
resume-aware state service, truthful step status (draft / applying /
applied / failed), and wizard shell that no longer treats
test-connection as completion. Refresh the integrations hub to expose
Secrets / Feed Mirrors / Object Storage categories and align the
onboarding wizard validation with the backend contract for
optional-auth local connectors.
Modernize the release-orchestrator environments pages against the new
environment/target API (models + client), plus adjacent navigation,
route-surface, and test-surface refresh. Add Playwright harnesses for
live setup-wizard bootstrap / integrations bootstrap / state truth
checks, and commit their evidence.
Closes UISETUP-* from SPRINT_20260413_003 and the UI-facing tasks of
SPRINT_20260413_004.
