Improvements and fixes

Production status now reflects a silent on-site agent, data logger swaps carry your components over, and Zebotec and QReader values stop dropping out.

• Your plant no longer shows as producing when the on-site agent has lost every data source or has just restarted without data.
• After you swap a data logger, your components move to the new one instead of staying on the old one.
• Your Zebotec inverter values now keep coming through even when the data logger is under load.
• A value you mapped on a QReader data logger no longer goes missing when its group name contains a dot.
• Security updates for third-party components.
