ui : fix badge guard for draft sidecars, keep parameter precision

hasBadges now counts draft sidecar badges, so a sidecar-only model still
renders. Billions keep one decimal for hub counts and stay bare for whole
values. Avatar failures track the org instead of the instance, and the
download progress bar no longer pulses while determinate.
