no issue
- Adds 'GET /members/:id/signin_urls' endpoint to Admin API allowing to fetch login URL for member. This URL allows to log in as a member which is useful in situations when you need to impersonate a member (for example to debug some issue they are having)
- Added member_signin_urls permission with migrations. Only the "Owner" user can read "signin_urls" resource. Admin and other users will be denied access
