cost service v13: lower per-VIN estimates to 3mc/10MB

Browse Source 
- Per-VIN marginal: 3 millicores / 10MB (was 50mc/80MB)
- Based on ~3000 VINs using ~10 cores / 30GB marginal on top of platform base
- Total fleet now shows realistic: 87 cores / 569GB for 2463 VINs
- Updated README with v13 output
