Add perfsage SLO reporting listener to the plugin registry (#817)

* Add perfsage SLO reporting listener to the plugin registry

* Remove SLOReporter from PerfSage plugin componentClasses

SLOReporter is a helper class, not a JMeter TestElement/GUI component.
componentClasses should list only discoverable JMeter components; the
listener SLOAnalysisListener remains as markerClass and sole component entry.

* Canonical-format various.json for format_repo.py CI check

Apply json.dumps(indent=2) style so "Check repo JSON formatting" passes.

* Update site/dat/repo/various.json (canonical JSON format)
