TestThreeMonthAgeCheck used 89*24h as "3 months minus 1 day", but
89 calendar days == exactly 3 months on dates like May 1 (Feb+Mar+Apr=
28+31+30=89). The equality case makes the >3-month eligibility check
return true instead of false. Replace with AddDate-relative anchors
so the test stays correct regardless of current date.

90 days == 3 calendar months exactly in March/April, causing
TestThreeMonthAgeCheck to fail. The intent is >= 3 months old.

Implements the full map lifecycle audit as a hourly ticker in the
matchmaker:
1. updateMapFairnessStats: recompute per-slot win counts from completed
matches into the map_fairness table
2. flagUnfairMaps: flag maps where any slot deviates >10pp from expected
(1/N) across 80+ matches → status='probation'
3. retireDislikedMaps: force-retire maps with >20 net negative votes
4. pruneLowEngagementMaps: monthly bottom-10% engagement prune per tier
5. promoteClassicMaps: top-5 all-time engagement, 3+ months → 'classic'
Matchmaker already filters retired maps and gives probation maps 50%
reduced selection probability in selectMapLRU.
