- Changed default sort order in 'Edit Group' modal to 'created_at' (newest first).
Previously it sorted by group membership, causing toggled users to invisible jump
to the top of the list (often changing pages). using a stable sort fixes this UX issue.
- Removed unnecessary `page = 1` reset in toggleMember function so admins
don't lose their place when selecting multiple users.
Bug 2 - Model Image Display Bug:
- Added `Cache-Control: no-cache, must-revalidate` headers to the model profile
image endpoint. This ensures that when a model avatar is updated, the browser
fetches the new image instead of serving a stale cached version (favicon).
Fixes#19885
