Service scan support

[attiasas]

• All tests passed. If this feature is not already covered by the tests, I added new tests.
• This pull request is on the dev branch.
• I used gofmt for formatting the code before submitting the pull request.
• Update documentation about new features / new supported technologies

---

Depends on:

• Missconfiguration service jfrog-client-go#1352
• Services (Missconfiguration) scan for source code jfrog-cli-security#815

Support scanning and reporting issues from Services (Missconfigurations) scan

Addressing the remaining review notes:

Summary goldens only covering “Not Scanned” — updated TestScanSummaryContent fixtures and the summary goldens so Services is scanned and shows severity details (vulns / violations / both).

TestGetNewReviewComments Services case — already covered in the “With issues for review comments” case (ServicesVulnerabilities + expected ServicesComment), added in 5dcebdf before the review. Leaving it bundled with IaC/SAST rather than adding a dedicated case.
