fix(ci): image pushes read the registry secrets that exist (#1275) (#1306)

Squash-merged by topher (jarvis principal) via break-glass API path (wrapper main-only gap, documented). Gates: CI 2492 green at head e19013ed, review 181 APPROVED (fred) at pinned head. Diagnostic merge: the push pipeline now exercises kaniko with the REGISTRY_* secrets - valid creds yield the first fully green gated publish; invalid yield an explicit 401.
