fix: correct URL validation regex and test assertions

- Update validateNetworkEndpoint regex to allow paths (/api/metrics)
- Fix SystemInfoTest expected values for boundary calculations
- Remove invalid test case (http://localhost is now valid)
- Use actual numeric values instead of expressions in CsvSource
