Missing information on machine dashboard

[dominicrutk]

On the machine-specific dashboard page, there is a table that should list all the backup events for that machine. This table has space for fields like transfer size, transfer time, exit code, and rsync exit reason. However, none of those fields are currently displaying at all (see attached screenshot).

As a beginner issue, each field can be fixed individually (as a separate feature branch). Once all the fixes are merged, this issue can be closed.
