Issue Description:

The site-level Analytics Permissions page (/wiki/analytics/permissions) becomes unresponsive and eventually times out on tenants with a large number of groups. After loading for several minutes, an error message is displayed and the page requires a full reload. This prevents admins from viewing or modifying analytics permission settings.

Steps to Reproduce:

1. Navigate to a Confluence Cloud site that has a large number of groups (e.g., 10,000+)
2. Go to Analytics → Permissions (/wiki/analytics/permissions)
3. Wait for the page to load
4. Attempt to add or remove group permissions

Expected Result:

The page loads within a reasonable time and allows admins to manage analytics permissions without errors.

Actual Result:

The page hangs during loading, eventually displays an error message, and requires a reload. No permission changes can be saved.

Impact:

• Site admins are unable to manage analytics permissions via the UI

• No public REST API is available as an alternative workaround

• Affects any tenant with a sufficiently large number of groups

Workaround:

• Attempt to remove permissions in small batches (a few groups at a time) before the page times out

• If that fails, backend intervention is required to clear the stored restrictions
