feat: 7-module VINchecker v2 — NICB, auction history, Florida DMV, theft stats, odometer fraud, safety ratings, risk score expansion

New modules: nicb.py, auction_history.py, dmv_florida.py, theft_stats.py, odometer_validator.py
Expanded risk.py with 8 new factors (NICB alert, safety rating, auction flags, odo validation, theft level, odo fraud, DMV lien, open VIN recalls)
PDF now has 11 sections including NICB check, theft stats, odometer fraud, odometer validation, auction history, Florida HSMV
AI prompt enriched with all new data fields
