Add Shopify inventory sync and order webhook

- Migration: shopify_variant_id on products_sizes, shopify_order_id on products_sales - ShopifyService: paginated REST client (2024-10 API) - shopify:map — one-time command to link variants by SKU - shopify:sync — reconciliation command (Shopify is master) - VerifyShopifyWebhook middleware: HMAC-SHA256 verification - ShopifyWebhookController: idempotent orders/paid handler, FIFO inventory deduction - Webhook route: POST /api/webhooks/shopify/orders-paid Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
