[Fix] Dead code cleanup: wire view_report_json(), remove 3 orphaned variables

[Fix] --json-report: call view_report_json() instead of inlining identical logic
[Fix] Remove orphaned $pidof variable (process detection uses pgrep)
[Fix] Remove orphaned $clamdscan variable (clamselector() discovers binary inline)
[Fix] Remove vestigial $coltest capability test (result never consumed)
