feat: Product New/Edit pages with comprehensive form

Implemented full Product CRUD create/edit functionality.

Product New Page (New.tsx):
✅ Create new products
✅ Page header with back/create buttons
✅ Form submission with React Query mutation
✅ Success toast & navigation
✅ Error handling

Product Edit Page (Edit.tsx):
✅ Load existing product data
✅ Update product with PUT request
✅ Loading & error states
✅ Page header with back/save buttons
✅ Query invalidation on success

ProductForm Component (partials/ProductForm.tsx - 600+ lines):
✅ Basic Information (name, type, status, descriptions)
✅ Product Types: Simple, Variable, Grouped, External
✅ Pricing (regular, sale, SKU) for simple products
✅ Inventory Management (stock tracking, quantity, status)
✅ Categories & Tags (multi-select with checkboxes)
✅ Attributes & Variations (for variable products)
  - Add/remove attributes
  - Define attribute options
  - Generate all variations automatically
  - Per-variation pricing & stock
✅ Additional Options (virtual, downloadable, featured)
✅ Form validation
✅ Reusable for create/edit modes
✅ Full i18n support

Features:
- Dynamic category/tag fetching from API
- Variation generator from attributes
- Manage stock toggle
- Stock status badges
- Form ref for external submit
- Hide submit button option (for page header buttons)
- Comprehensive validation
- Toast notifications

Pattern:
- Follows PROJECT_SOP.md CRUD template
- Consistent with Orders module
- Clean separation of concerns
- Type-safe with TypeScript
