Update retries in playwright config and refactor account settings

This update changes the number of retries in the Playwright configuration. Additionally, solid improvements have been made in the account settings, including better data semantics for testing, changes to email confirmation, and adding a new E2E test suite for accounts. The sign-up flow was updated and problems with multi-language support logic were fixed.
