Drops signalSource/triangulated from municipalityUpdate (migration
simplify_municipality_signal_fields), rewrites signal-type labels for the
field team, and treats any adversary signal as confirmed in E11 (P1
triage 1). Also fixes the stale post-B43 leader-home e2e and lowers a
drifted bypass pin.
Fold duplicated campanha access, loaders, list/filter/form shells, and scripts into shared modules; reorganize utilities by domain; stabilize e2e; and document prevention-first audit workflow so the same smells cannot creep back in.
