feat(network-statistics): add total members and leg count properties with localization

- Introduced new properties for total members, left leg count, and right leg count in the NetworkStatisticsDto class to enhance data representation.
- Added localization comments in Persian for better understanding of the new properties.
- Updated the .gitignore file to ensure consistency with the latest Visual Studio ignore patterns.

These changes improve the clarity and usability of the network statistics, providing a more comprehensive view of member distribution.
