Added FOCUS-40095 - User Profiles: New Login as Parent Profile Permission

This enhancement adds a new User Profile permission named "Login as Parent." When enabled, this permission allows a user to log in as Parent User types, but not as other admin or teacher-related users. The permission will be initially set to the off position, preserving current functionality. Additionally, the existing User Profile Permission "Login As" remains unchanged by this update and will continue to permit end users to log in as all user types.
