Previous commit (e931f77) only fixed GetAllProductsAsync and GetProductByIdAsync.
This commit fixes GetProductsByCategoryAsync which also had the broken filtered Include syntax.
**Impact**: Variants will now appear when browsing products by category in TeleBot.

Critical bug where ProductVariants were never loaded from database.
**Problem:**
`.Include(p => p.Variants.Where(v => v.IsActive))` syntax was NOT
generating SQL JOIN statements in EF Core 9.0, causing all products
to return empty variants array even when variants exist in database.
**Solution:**
- Changed to simple `.Include(p => p.Variants)`
- Filtering still happens in DTO mapping (Select statement)
- Only IsActive variants are returned to API consumers
**Impact:**
- TeleBot can now display product variants with selection UI
- Variant pricing and stock levels now visible to customers
- Multi-variant products (e.g., Size/Color) now functional
**Test Case:**
Product 131cc3ad-07f4-4ec9-89ca-b05a0b4cfb41 has 7 variants:
- Size: Small, Medium, Large, XL
- Color: Black, White, Navy Blue
These will now appear in API responses and TeleBot UI.

Enables individual variants to have their own prices, overriding the base product price.
**Database Changes:**
- Added Price (decimal?, nullable) to ProductVariants table
- Added ProductVariantId to OrderItems table with foreign key relationship
- Created index on OrderItems.ProductVariantId for performance
**API Changes:**
- ProductVariantDto: Added Price field
- CreateProductVariantDto: Added Price field with validation
- UpdateProductVariantDto: Added Price field
- OrderItemDto: Added ProductVariantId and ProductVariantName
- CreateOrderItemDto: Added ProductVariantId
**Business Logic:**
- OrderService: Variant price overrides base price (but multi-buy takes precedence)
- ProductService: All variant CRUD operations support Price field
**Admin UI:**
- CreateVariant: Price input with £ symbol and base price placeholder
- EditVariant: Price editing with £ symbol
- ProductVariants list: Shows variant price or "(base)" indicator
**Client Library:**
- Updated all DTOs to match server-side changes
- Full support for variant pricing in order creation
**Migration:**
- EF Core migration: 20251003173458_AddVariantPricing
- Backward compatible: NULL values supported for existing data
**Use Case:**
Products with size/color variants can now have different prices:
- Small T-shirt: £15.00 (variant override)
- Medium T-shirt: £18.00 (uses base price)
- Large T-shirt: £20.00 (variant override)
