Created a scratch team 5, booted all 16 of its containers, snapshotted its
footprint, deleted it via the API, and re-snapshotted:
before: 16 containers, 1 sidecar, team5_default network, teams/team5 dir
after : 0 containers, 0 sidecars, network gone, dir GONE, 34 UFW ports
closed, Traefik domain removed, 0 score rows
took 102s; the other 4 teams (64 containers, receivers active) were
untouched and still at 64/64 SLA.
Adds panel/team_footprint.sh (before/after proof of a delete),
team_health.sh, watch_load.sh.
