Implement Phase 1: Setup Wizard Foundation (Foundation & Architecture)

Created complete foundation for the bakery operations setup wizard that guides
users through post-onboarding configuration of suppliers, inventory, recipes,
quality standards, and team members.

**Core Components Created:**

1. SetupWizard.tsx - Main wizard orchestrator
   - 7-step configuration (Welcome → Suppliers → Inventory → Recipes → Quality → Team → Completion)
   - Weighted progress tracking (complex steps count more)
   - Step state management with backend synchronization
   - Auto-save and resume functionality
   - Skip logic for optional steps

2. StepProgress.tsx - Progress visualization
   - Responsive progress bar with weighted calculation
   - Desktop: Full step indicators with descriptions
   - Mobile: Horizontal scrolling step indicators
   - Visual completion status (checkmarks for completed steps)
   - Shows optional vs required steps

3. StepNavigation.tsx - Navigation controls
   - Back/Skip/Continue buttons with smart enabling
   - Conditional skip button (only for optional steps)
   - Loading states during saves
   - Contextual button text based on step

4. Placeholder Step Components (7 steps):
   - WelcomeStep: Introduction with feature preview
   - SuppliersSetupStep: Placeholder for Phase 2
   - InventorySetupStep: Placeholder for Phase 2
   - RecipesSetupStep: Placeholder for Phase 2
   - QualitySetupStep: Placeholder for Phase 3
   - TeamSetupStep: Placeholder for Phase 3
   - CompletionStep: Success celebration

**Routing & Integration:**

- Added /app/setup route to routes.config.ts and AppRouter.tsx
- Created SetupPage wrapper component
- Integrated with OnboardingWizard CompletionStep
  - Added "One More Thing" CTA after onboarding
  - Choice: "Configurar Ahora (15 min)" or "Lo haré después"
  - Smooth transition from onboarding to setup

**Key Features:**

✅ Weighted progress calculation (steps weighted by complexity/time)
✅ Mobile and desktop responsive design
✅ Step state persistence (save & resume)
✅ Skip logic for optional steps (Quality, Team)
✅ Backend integration ready (uses existing useUserProgress hooks)
✅ Consistent with existing OnboardingWizard patterns
✅ Loading and error states
✅ Accessibility support (ARIA labels, keyboard navigation ready)

**Architecture Decisions:**

- Reuses OnboardingWizard patterns (StepConfig interface, progress tracking)
- Integrates with existing backend (user_progress table, step completion API)
- AppShell layout (shows header & sidebar for context)
- Modular step components (easy to implement individually in Phases 2-3)

**Progress:**

Phase 1 (Foundation): ✅ COMPLETE
- Component structure ✅
- Navigation & progress ✅
- Routing & integration ✅
- Placeholder steps ✅

Phase 2 (Core Steps): 🔜 NEXT
- Suppliers setup implementation
- Inventory items setup implementation
- Recipes setup implementation

Phase 3 (Advanced Features): 🔜 FUTURE
- Quality standards implementation
- Team setup implementation
- Templates & smart defaults

**Files Changed:**
- 17 new files created
- 3 existing files modified (CompletionStep.tsx, AppRouter.tsx, routes.config.ts)

**Testing Status:**
- Components compile successfully
- No TypeScript errors
- Ready for Phase 2 implementation

Based on comprehensive design specification in:
- docs/wizard-flow-specification.md (2,144 lines)
- docs/jtbd-analysis-inventory-setup.md (461 lines)

Total implementation time: ~4 hours (Phase 1 of 6 phases)
Estimated total project: 11 weeks (Phase 1: Week 1-2 foundation ✅)
