fix(review): full code-review remediation — 5 High + Medium/Low across 16 modules

Remediation from the full per-module code review at 4307c381 (findings recorded
separately in code-reviews/).

Highs fixed:
- DeploymentManager-025/SiteRuntime-031: stop broadcasting notification lists + SMTP
  configs (incl. credentials) to sites; site purges already-persisted rows on apply
  (enforces the central-only delivery design; clears plaintext SMTP creds at rest).
- DataConnectionLayer-023: guard the native-alarm subscribe path against the
  mid-flight-unsubscribe adapter-feed leak (mirrors the DCL-021 tag-path fix).
- SiteEventLogging-024: normalize From/To query bounds to UTC (the -016 fix the
  audit trail claimed but never committed).
- KpiHistory-001: add an in-flight guard to the recorder sample tick.
- ScriptAnalysis-001: harden the trust analyzer's TPA-absent fallback (resolve
  forbidden anchors in the minimal reference set; warn on degraded mode) — anchors
  added to validation references only, never the compile gate.
(InboundAPI-026 left to the feat/ipsen-movein effort per owner decision.)
