Refactor e2e test code and reduce test timeout

The end-to-end tests have been refactored for clarity and maintainability. This includes changes in how the 'Billing' link is accessed, addition of comments and small coding improvements. Moreover, the test timeout has been reduced from 2 minutes to 1 for efficiency. Changes were also applied to the text content in locales file and minor fixes in component styling.
