Refactor E2E tests, update utils, and modify plan-picker validation

Several changes have been made to optimize the testing and validation workflows. The end-to-end tests for user billing, invitations, account, team billing, and team accounts have been retouched for improved performance and better accuracy. There has been a minor modification in the validation rules for plan-picker in the billing component. Furthermore, modifications are made to several utility functions to fine-tune their operations.
