  default export's 3 inline date/time calls.
- IntegrationStatusTabs: thread tz through fmtDate helper +
  VeeamTab sub-component prop.
- SyncScheduler: thread tz into closure-scoped formatDate helper.
- audit-log-table, user-table, user-sessions, active-sessions: inline
  toLocale calls in component body.
- analysis-view: useUserTimezone in AnalysisView; thread tz into 4
  toLocaleString calls.
- resolution-trend, volume-trend (recharts): module-scope fmtDate(iso)
  → fmtDate(iso, tz); useUserTimezone in named export; thread tz into
  axis tickFormatter + tooltip labelFormatter.
- ticket-detail-modal: thread tz into formatDate arrow inside
  TicketDetailModal.
- TimelineView: useUserTimezone; thread tz into 4 toLocale*String calls
  (hour/day/month/event-time formatters).
- ScoreCard: useUserTimezone in AggregateScoreCard; thread tz into the
  date-range latest call.
- addigy-tab: useUserTimezone in AddigyTab; thread tz into 2 inline calls.
- activity-sparkline: module-scope fmtHour(iso) → fmtHour(iso, tz);
  useUserTimezone in ActivitySparkline; update 3 callsites in title/aria.
- compliance-detail-table: thread tz from ComplianceDetailTable into
  ContractCoverageModal sub-component (2 inline date calls).
- company-backup-detail: module-scope formatDate(d) → formatDate(d, tz);
