refactor(test): cookie consent handling and remove global setup This commit refactors the cookie consent handling by introducing a reusable `acceptCookiesIfBanner` utility function. This function encapsulates the logic for finding and clicking "Accept All" buttons, making it adaptable to various selectors. The `global-setup.ts` file has been removed, as its functionality is now covered by the new utility function integrated into individual test `beforeEach` hooks. The Playwright configuration has been updated to reflect this change. This change improves the maintainability and reusability of cookie consent logic across the test suite.
