Improvements and fixes

The day power chart now marks only connection losses that really happened and names the remote access connection that dropped. The record of remote access activity opens on the most recent weeks.

• On a plant without remote access, the day power chart no longer marks the whole day as a lost connection.
• Where a connection really dropped, the chart now names the remote access connections affected, or states that their state is unknown.
• The record of remote access activity opens on the most recent weeks, and the weekday labels stay in place while scrolling.
