Issue Summary

Jira Cloud app for Slack: "Don't show again" preference for sign-in nudge does not persist across workspaces in Slack Enterprise Grid.

Steps to Reproduce

1. Use a Slack instance configured with Enterprise Grid (multiple workspaces).

1. Install the Jira Cloud for Slack app.

1. As an unauthenticated user, post a Jira link in Workspace A to trigger the "Sign-in to enable Jira previews" nudge.

1. Click the "Don't show again" button on the nudge.

1. Navigate to Workspace B within the same Enterprise Grid and post a Jira link.

Expected Results

The "Don't show again" preference should be respected app-wide (or Org-wide), and the user should not be prompted with the sign-in nudge again.

Actual Results

The user is re-prompted with the same sign-in nudge in Workspace B. The dismissal is currently scoped only to the specific (slackUserId, workspaceId) pair where the click occurred, rather than the global user identity.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available

Affected users can sign in to the Jira Cloud for Slack app once. The sign-in nudge is only shown to unauthenticated users; once a user is authenticated and the account mapping is established, the nudge logic is bypassed entirely.
