✅ [RUM-17233] Add Shopify checkout views and actions e2e test

[lierniel]

Motivation

RUM-17233: cover the Shopify integration with e2e tests. The dedicated browser-rum-shopify bundle (#4878) explicitly scoped e2e tests out; this closes that gap by exercising the full checkout flow against a real Shopify dev store.

Changes

• Added e2e test framework support for Shopify: buildShopifyUrl/unlockShopifyStorePassword (dev store password gate), withShopifyApp()/shopifySetup (intercepts the CDN bundle request and injects RUM configuration into both the storefront's Theme Liquid snippet and the checkout's Custom Pixel sandbox), and a getShopifyStorePassword() secret accessor.
• Added shopify.scenario.ts, covering the full flow: storefront → product page → add to cart → checkout → thank-you page → back to storefront. Asserts:
  • A single session id shared across the Theme Liquid and Custom Pixel SDK instances
  • 5 ordered view events with the correct URLs (checkout/thank-you matched via the same path regex used in browser-rum-shopify)
  • Ordered click actions with the correct target and page for each
  • No unexpected browser console errors, filtering known store-side noise
• Runs serially with a 15s cooldown between invocations, and test.slow(), since this hits a live dev store that's sensitive to request volume (Cloudflare bot protection, checkout rate limiting) and the full flow runs close to the default test timeout.

Test instructions

To run locally:

SHOPIFY_STORE_PASSWORD=<dev store password> yarn test:e2e -g "shopify"

Or trigger the according pipeline on the gitlab: https://gitlab.ddbuild.io/DataDog/browser-sdk/-/pipelines

Chromium only (--disable-web-security is required to bypass the dev store's CSP/CORS restrictions). Runs against the live custom-pixel-e2e.myshopify.com dev store, so repeated back-to-back local runs may need a few minutes' gap to avoid tripping Cloudflare's verification wall.

Checklist

• Tested locally
• Tested on staging
• Added unit tests for this change.
• Added e2e/integration tests for this change.
• Updated documentation and/or relevant AGENTS.md file
