improve network error handling, oauth2 logic cleanup, tls settings, and ui/test updates (#4444)

~ axios error interceptor fixes and timeline network logs ui updates
~ axios instance error interceptor now returns promise rejects instead of plain objects
~ fixed digest_auth regression
~ removed the interceptor logic for the oauth2 token url calls
~ timeline network logs ui updates
~ updated oauth2 test collections

* ssl/tls fixes and error handling
~ set the min allowed tls version to 1.0 (TLSv1)
~ proxy/certs/tls setup error handling

* enhance JSON stringification with circular reference handling
- Add getCircularReplacer to safely handle circular references in objects
- Update safeStringifyJSON to support indentation and handle undefined values
~ we currently support digest auth for bruno-cli
