fix(web): enhance throughput display in health check results

- Updated the health check results display to show download and upload speeds separately.
- Introduced a new `fmtSpeed` function to format speeds in KB/s or MB/s for better readability.
- Removed the previous single speed display and replaced it with a more informative output.

These changes improve the clarity of health check results, providing users with a better understanding of network performance.
