Remote access can now be handed to a technician without an account

Remote access to a plant can now be handed to an external technician as a link with its own password, without an account. The page behind the link provides the connection file, shows whether the connection is live, and lets the technician read the server's settings and log and test their own side.

• Sharing issues new keys, so connection files handed out earlier stop working and current connections drop.
• "Diagnostics" runs a ping and a port check against the remote-access address and the networks behind it.
• "Server configuration" and "Server log" show what the router must match and what the server reports.
• The same port check can be run on a plant's remote access, or requested from the assistant.
• Every visit, download, check and log view the technician made is listed.
