CNF-23887: Populate JUnit XML timestamp, hostname, and duration

[sebrandon1]

Summary

• Populate timestamp, hostname, and time attributes on the JUnit XML <testsuite> element — these are standard JUnit attributes expected by CI systems like Prow and Jenkins
• Add Duration field to ScanResults, computed centrally in assembleResults
• Add duration_seconds (float64) to JSON output for human-readable scan timing (time.Duration is suppressed from JSON since it serializes as nanoseconds)

Jira: CNF-23887

Before

<testsuite name="TLSSecurityScan" tests="52" failures="0" time="0">

After

<testsuite name="TLSSecurityScan" tests="52" failures="0" time="1754.187"
           timestamp="2026-05-14T13:59:05-05:00" hostname="bpalm-mac">

JSON output (new field)

{
  "timestamp": "2026-05-14T13:59:05-05:00",
  "duration_seconds": 1754.19
}

Test plan

• go build ./... passes
• go test ./... passes
• Live scan against cnfdt16 cluster with --junit-file and --json-file confirms all three attributes populated
• Existing JUnit test updated to assert new fields
