feat(checkout): Send new params to the create widget URL

[jeetparikh]

• Send additional params to the create widget URL
• Remove the API call to get nft transaction id as it is not needed any more

---

Note

Switch to Immutable widget-url endpoint with new snake_case NFT params, remove Transak nft-transaction-id call, use numeric gas limit, and add strict referrerPolicy to iframes.

• Transak NFT checkout flow:
  • Build widget URL via POST {IMMUTABLE_API_BASE_URL}/checkout/v1/widget-url using new snake_case fields: is_nft, contract_id, crypto_currency_code, calldata, nft_data, estimated_gas_limit, etc.; conditionally include email and exclude_fiat_currencies.
  • Map nftData to new schema (collection_address, image_url, nft_name, nft_type, price, quantity, token_id).
  • Remove previous Transak nft-transaction-id API call and related param.
  • Use numeric MAX_GAS_LIMIT and send numeric estimated_gas_limit.
• Iframes:
  • Add referrerPolicy: strict-origin-when-cross-origin to TransakIframe and on-ramp iframe.

Bug: useEffect missing dependency on getNFTCheckoutURL

The useEffect hook has an empty dependency array but calls getNFTCheckoutURL, which depends on contractId, environment, transakParams, and onError. When these dependencies change, getNFTCheckoutURL is recreated but the effect never re-runs to call the updated function, so the iframe will not refresh with new data.

	useEffect(() => {
	(async () => {
	const checkoutUrl = await getNFTCheckoutURL();
	setIframeSrc(checkoutUrl);
	})();
	}, []);
