Dead-code audit batch 1: five functions with zero references from main,
tests, or pulse-enterprise (deadcode -test, grep-verified per symbol,
enterprise compile-checked). Also renames the tlsutil test that
exercised the deleted compat alias's target to name the Unverified
function it actually calls.
Skipped from the audit list after re-verification: IsNilAlertPayload
(live pulse-enterprise consumer in internal/aialertanalysis).
Retire runtime/API/UI monitored-system volume enforcement now that infrastructure monitoring is no longer capped.
Keep only legacy metadata scrubbing and purchase-start compatibility for old max_monitored_systems references.
Rename the remaining preview surface to monitored-system impact and make previews explanatory rather than save-blocking.
Update subsystem contracts and RA7 evidence for the caps-retired invariant.
