Improved monitoring of the connection to the MKG server

To ensure the proper functioning of Shop Floor, a connection to the MKG server is required. If a connection cannot be established, the following message will now be displayed: "Connection to the MKG server failed. Please check your internet connection and restart your device if necessary. After 7 days without a connection, the application will be locked. Please contact the helpdesk or system administrator."

After 7 days without a connection to the MKG server, Shop Floor will be blocked, and the following message will be displayed: "The application is locked because there has been no connection to the MKG server for more than 7 days. Please contact the helpdesk or system administrator."
