Replace Connection return origins

Compare-and-replace the authenticated Workspace’s complete Connection return-origin allowlist. Removing an origin blocks new ceremonies immediately while an already-reserved ceremony keeps only its frozen non-extendable handoff until expiry; an Idempotency-Key makes an ambiguous exact retry safe.

Checkfu support posture: alpha; hosted. Required evidence journey: connection-lifecycle. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
