Add last_detected_at and last_matched_at tracking

Browse Source 
Track when cookies are last detected (last_detected_at on cookies)
and when patterns last matched a detected cookie
(last_matched_at on cookie_patterns). The cookie timestamp is
refreshed on every detection report; the pattern timestamp is
computed as MAX(last_detected_at) during pattern analysis.
