Add account deletion process and improve tests

The commit introduces a message to indicate the account deletion process. It also enhances the tests by reducing code redundancy in the e2e tests, creating a more random name for team accounts, and improving the navigation process after account deletions. The commit also includes code cleanup tasks, such as the removal of unused imports.
