Update Admin Login

Update existing admin login for company.
Admin login DOESN'T HAVE EMPLOYEE ROLE AND CAN'T BE USED FOR PAYROLL CALCULATIONS.
You can call Add New Employee endpoint instead of this endpoint or you can call it later. System then connect Admin and Employee accounts together.
Pairing is done via email address comparison.

This endpoint can be called only by System and Admin level users.

Employee call will return Forbidden result even for Employee own company.
