feat: Complete frontend i18n implementation for dashboard components

- Updated TypeScript types to support reasoning_data field
- Integrated useReasoningTranslation hook in all dashboard components:
  * ActionQueueCard: Translates PO reasoning_data and UI text
  * ProductionTimelineCard: Translates batch reasoning_data and UI text
  * OrchestrationSummaryCard: Translates all hardcoded English text
  * HealthStatusCard: Translates all hardcoded English text
- Added missing translation keys to all language files (EN, ES, EU):
  * health_status: never, critical_issues, actions_needed
  * action_queue: total, critical, important
  * orchestration_summary: ready_to_plan, run_info, took, show_more/less
  * production_timeline: Complete rebuild with new keys
- Components now support fallback for deprecated text fields
- Full multilingual support: English, Spanish, Basque

Dashboard is now fully translatable and will display reasoning in user's language.
