Improvements and fixes

Connection state after an on-site agent restart is right again: logger status, expected production, no false offline reports, and events explained in words.

• You see a data logger's status in the app again straight after your on-site agent restarts.
• Your plants no longer report their network as offline while it is still reachable.
• On large plants, expected production no longer stalls or counts energy twice after your on-site agent restarts.
• An event about your plant's connection now says in words why it opened and what ended it.
• Security updates for third-party components.
