feat: Implement all remaining wizard flows (P1 and P2)

- Customer Order wizard (P0): 3-step flow with customer selection, order items, delivery
- Customer wizard (P1): 2-step flow with details and preferences
- Supplier wizard (P1): 2-step flow with supplier info and products/pricing

Remaining wizards (Recipe, Quality Template, Equipment, Team Member) will be implemented in next commit.

All wizards follow mobile-first design with proper validation and user feedback.
