Fix the path mismatch between /acl/endpoints API and actual routes:
- Users: /users/{id} → /access/users/{id}
- Groups: /groups/{id} → /access/groups/{id}
- Roles: /roles/{id} → /access/roles/{id}
This fixes the error where creating ACE entries fails with:
"Path '/groups/{id}' doesn't match any existing endpoint"
The actual routes are registered under /access/ prefix, but the
endpoints API was returning paths without the prefix.
