Google sign-in is available again on canary.tuist.dev

The ‘Log in with Google’ button was missing on canary.tuist.dev because the environment’s Google OAuth credentials were not configured. The Helm chart now sources those credentials from 1Password via External Secrets Operator, so Google sign-in is restored on canary and remains available on production and staging. Self-hosted deployments can also opt into the same managed-secrets setup.
