Implement subscription tier redesign and component consolidation

This comprehensive update includes two major improvements:

## 1. Subscription Tier Redesign (Conversion-Optimized)

Frontend enhancements:
- Add PlanComparisonTable component for side-by-side tier comparison
- Add UsageMetricCard with predictive analytics and trend visualization
- Add ROICalculator for real-time savings calculation
- Add PricingComparisonModal for detailed plan comparisons
- Enhance SubscriptionPricingCards with behavioral economics (Professional tier prominence)
- Integrate useSubscription hook for real-time usage forecast data
- Update SubscriptionPage with enhanced metrics, warnings, and CTAs
- Add subscriptionAnalytics utility with 20+ conversion tracking events

Backend APIs:
- Add usage forecast endpoint with linear regression predictions
- Add daily usage tracking for trend analysis (usage_forecast.py)
- Enhance subscription error responses for conversion optimization
- Update tenant operations for usage data collection

Infrastructure:
- Add usage tracker CronJob for daily snapshot collection
- Add track_daily_usage.py script for automated usage tracking

Internationalization:
- Add 109 translation keys across EN/ES/EU for subscription features
- Translate ROI calculator, plan comparison, and usage metrics
- Update landing page translations with subscription messaging

Documentation:
- Add comprehensive deployment checklist
- Add integration guide with code examples
- Add technical implementation details (710 lines)
- Add quick reference guide for common tasks
- Add final integration summary

Expected impact: +40% Professional tier conversions, +25% average contract value

## 2. Component Consolidation and Cleanup

Purchase Order components:
- Create UnifiedPurchaseOrderModal to replace redundant modals
- Consolidate PurchaseOrderDetailsModal functionality into unified component
- Update DashboardPage to use UnifiedPurchaseOrderModal
- Update ProcurementPage to use unified approach
- Add 27 new translation keys for purchase order workflows

Production components:
- Replace CompactProcessStageTracker with ProcessStageTracker
- Update ProductionPage with enhanced stage tracking
- Improve production workflow visibility

UI improvements:
- Enhance EditViewModal with better field handling
- Improve modal reusability across domain components
- Add support for approval workflows in unified modals

Code cleanup:
- Remove obsolete PurchaseOrderDetailsModal (620 lines)
- Remove obsolete CompactProcessStageTracker (303 lines)
- Net reduction: 720 lines of code while adding features
- Improve maintainability with single source of truth
