Add an employee through a PIM page object, with unique test data

Interview scenario

"The PIM module is where most of our regression lives. Build a LoginPage and a PimPage, a fixture that logs in as Admin, and a test that adds a new employee with a unique name and proves the personal details page shows it. The demo database is shared with the whole internet, so your data must not collide."

Acceptance criteria

1. pages/login.page.ts exports LoginPage with goto() and login(username, password).
2. pages/pim.page.ts exports PimPage with addEmployee(firstName, lastName) and employeeName() (the heading on the personal details page).
3. fixtures.ts extends test with a pim fixture that logs in and opens the Add Employee page.
4. tests/employee.spec.ts adds an employee whose last name contains a unique suffix (for example Date.now()) and asserts the heading shows the full name.
