Enhance browser configuration and path retrieval

- Updated `config.py` to include a comprehensive browser configuration section, allowing for dynamic retrieval of browser paths and drivers for Chrome, Edge, Firefox, and Brave.
- Refactored `new_signup.py`, `new_tempemail.py`, and `oauth_auth.py` to utilize the new browser configuration, improving flexibility and maintainability.
- Removed deprecated `get_default_chrome_path` function and replaced it with a more generalized `get_default_browser_path` function in `utils.py`.
- Updated localization files to include new strings related to browser path validation and selection.
