chore(release): v1.4.45 — analytics 9 s perf fix + audit-marathon closure + v1.4.44 hotfix merged

Audit-marathon close: 14 waves + W10 QA + reconcile. Perf fix (analytics 9 s -> 2-3 s), Zod multi-issue rollout (41 routes), Withings parked-state automation, mobile-UI WCAG 2.5.5 close, QoL i18n + offline banner + account delete, security PII drop + replay-injection scan. Migration 0075 required. Tests 4815 -> 5076.
