Per-facility environmental compliance history with a derived violator risk score and verdict API

Pulls a facility's EPA Detailed Facility Report (by ECHO Registry ID) and derives a 0-100 compliance risk score plus a plain-English verdict (clean/minor/elevated/high/severe), driven by EPA's own Significant Noncompliance flags, quarters-in-noncompliance, formal actions and penalties across air/water/waste programs. Answers 'Is this facility an environmental violator?', 'How severe and persistent are its violations?'.
