fix(admin): show real node tallies on team cards, not dead counters

TeamCard displayed team.stats.{calls,nominal,anomalous,critical}, but
nothing has called recordEvent since the simulator was removed, so every
card read "0 · 0 · 0 · 0" - in the pre-pivot classifier vocabulary.

Admin already had real per-team tallies from useCollective.counts (derived
from the node activity stream, and already used for totalFlashes); they
just were not passed down. Cards now show agent runs / flashes / errors,
with errors only rendered when non-zero.

Same root cause as the AddDocument telemetry removed in 5a5810a.
