feat(traffic-flow): enhance traffic classification and map display

- Added a new state variable `mapAsnLoaded` to track ASN loading status in the NetworkMapPage.
- Updated the page to conditionally display a message when ASN data is not loaded, improving user feedback.
- Enhanced traffic classification tests to include additional scenarios for Google and YouTube services, ensuring comprehensive coverage.
- Introduced a new function `pickMapInternetDest` to improve destination selection logic in traffic flow processing.
- Updated the traffic flow destination classification to handle new conditions and improve accuracy.
