Display memory as MB in live dashboard

Browse source 
With kilobyte the resulting numbers got too large and were cut off
in the charts, making them useless. However, even an idle Akkoma
server’s memory usage is in the lower hundreths of megabytes, so
we don’t need this much precision to begin with for the dashboard.

Other metric users might prefer base units and can handle scaling in a
smarter way, so keep this configurable.
