Use IEC MiB units on dashboard

1) physmem calculation is already in MiB
2) swapinfo -m actually reports in MiB - good
3) The code that gathers the disk space data already uses "df -h" which reports in IEC units, but the output just has the single char "M", "G" etc. We can always add "iB" here....

Use IEC KiB MiB GiB TiB units
