fix: use rsync --stats total when per-file sizes are missing

With --info=progress2, fast transfers skip the 100% progress line so
per-file sizes are 0. Fall back to distributing the aggregate total
from rsync --stats across groups weighted by file count. Also widen
the size column to 18 chars for proper alignment.
