Update dependencies and refactor page navigation logic

* Added `@wdio/cli` as a development dependency for improved test command handling.
* Refactored URL construction in the `Page` class to enhance clarity and maintainability.
* Updated import statements in `Subscribing.page.ts` for consistency and removed unnecessary options in the constructor.
