Fix Activity Log timezone formatting

[neubig]

Summary

• Format Activity Log run timestamps using the automation trigger timezone instead of the viewer's browser timezone.
• Show the timezone abbreviation in Activity Log timestamps when a timezone is configured.
• Read timezone from trigger.timezone while preserving the existing top-level fallback used by mocks/legacy data.

Tests

• cd frontend && npm run make-i18n && npm test -- src/__tests__/components/automations/detail/activity-log-item.test.tsx src/__tests__/components/automations/detail/activity-log-section.test.tsx src/__tests__/routes/automation-detail.test.tsx
• cd frontend && npm run typecheck
• cd frontend && npx eslint src/components/automations/detail/activity-log-item.tsx src/components/automations/detail/activity-log-section.tsx src/components/automations/detail/configuration-section.tsx src/routes/automation-detail.tsx src/__tests__/components/automations/detail/activity-log-item.test.tsx src/types/automation.ts && npx prettier --check src/components/automations/detail/activity-log-item.tsx src/components/automations/detail/activity-log-section.tsx src/components/automations/detail/configuration-section.tsx src/routes/automation-detail.tsx src/__tests__/components/automations/detail/activity-log-item.test.tsx src/types/automation.ts
