fix(admin): drop processed count from RUNNING import card

The whole document load commits in one transaction, so a live counter
sits at 0 for the entire run and only jumps to the final number on
completion. Showing "0" next to the spinner read as "nothing happening"
and prompted repeated retriggers. Render just the spinner + running
label until the DONE branch displays the final processed count.
