Changes

Port of PR #740 onto the v5.0.0 branch.

🐛 Fix: HostedCart — refresh minicart URL when persistKey changes (Closes #685)

• Added loadedOrderIdRef to track which order ID the current src was built for
• Added persistKey to useEffect dependency array so the cart URL recomputes when the storage key changes
• Fixed setOrder org-config lookup to use order?.id ?? orderId consistently
• Added regression test in specs/orders/hosted-cart.spec.tsx

📦 Deps: bump @commercelayer/organization-config to ^2.8.4

• Unlocks new ConfigParams fields: identityType, clientId, scope, returnUrl, resetPasswordUrl, skuListId, skuId, lang, token

✨ Feat: MyIdentityLink — pass all identity params to getOrganizationConfig

• Forwards identityType, clientId, scope, returnUrl, resetPasswordUrl
• Moved getDomain(endpoint) inside the useEffect callback to keep deps clean
• Fixed useEffect dependency array to include all consumed props

✨ Feat: AddToCartButton — pass skuListId and skuId to getOrganizationConfig

• Enables org-config URL templates with :sku_list_id and :sku_id placeholders to resolve correctly

♻️ Refactor: HostedCart — resolve order ID once via resolvedOrderId

• Extracted order?.id ?? localStorage.getItem(persistKey) into a single resolvedOrderId variable

Note: version bump commits from the original PR were intentionally skipped. The @commercelayer/sdk version conflict (PR used ^6.x, v5 uses ^7.x) was resolved by keeping the v5 SDK version.
