gitlab-migrations fails on Staging due to missing secret "gitlab-redis-actioncable-rails-credential-v1" (Severity 4)

Problem: gitlab-migrations failed on Staging because a required secret was missing.

Impact: Deployments to Staging were blocked, delaying development and testing work until the missing secret was added.

Causes: A recent change introduced a new secret required for gitlab-migrations, but the secret was missing from the Staging environment.

Response strategy: A fix was created and merged to add the missing secret. The deployment was retried after the fix.
