Improved error messages for missing license or inactivity

If a Shop Floor user could not log in due to no available licenses or inactivity, an unclear error message related to a cookie issue was displayed. These error messages have been improved in these cases: "Maximum number of sessions exceeded. The maximum number of logged-in sessions has been reached. Close other sessions and try again later." or "The user you are trying to log in with may not be active, no longer exists, or is not licensed.".
