Problem Description: Syncing Remote Registry throws a permission error in UI.

Reproduce:
1. create a test user without permissions
2. go to `/ui/registries`
3. click on`Sync from registry`

Proposed Solution:

• Hide the `Sync from registry` button when the user doesn't have permission.
• Display the button when the user has permission (`Change remote registry` permission).

In Remote Repo management (`/ui/repositories?tab=remote`), the kebab with syncing is hidden correctly when a user doesn't have permission. It should be unified all over the app.
