/**
 * Generic utility to wait for and configure a page by URL.
 *
 * Uses a dual strategy to handle the TOCTOU race condition where a page
 * opens between the context.pages() check and the waitForEvent listener:
 *   1. Check context.pages() for an existing matching page
 *   2. If not found, race waitForEvent('page') against polling
 *
 * @param context - Browser context to search for pages
 * @param pageUrl - Partial URL to match (e.g., 'notification.html')
 * @param viewport - Optional viewport size
 * @returns Promise that resolves to the found and configured page
