/**
 * Shared setup utility to handle common test initialization steps like logging in,
 * resetting files, and importing data, with the ability to run certain setup steps
 * only once per test suite based on a unique identifier (`id`).
 *
 * @param {string} id - A unique identifier to track setup execution and ensure certain steps (e.g., reset files, import data) run only once.
 * @param {Page} page - Playwright's Page object for interacting with the browser.
 * @param {SharedSetupOptions} options - Configuration options for the setup, including:
 *   - login: Whether to log in to the application.
 *   - resetFiles: Whether to reset files before tests.
 *   - importData: Path to the data to be imported into the database.
 *   - afterSetup: A custom function that runs once after the setup is complete.
 *   - resetAlways: When true, run resetFiles/importData on every call (not only the first for this id).
 *     Use when tests mutate app state (e.g. create content types) so retries and later tests start clean.

 *
 * WARNING:
 * Using `sharedSetup` in this way introduces a risk of tests becoming dependent
 * on the order in which they are executed. This could be dangerous because the execution order
 * is not guaranteed during retries in the CI.
 *
 * This approach should primarily be used when the setup time is significant and the tests don't
 * depend on each other's side effects.
