cost service: add per-VIN estimate derivation from actual metrics

Based on cec-prd-cluster-1 data (2026-02-05):
- Event Hubs: ~90M msgs/hr, ~230GB/hr
- Active VINs: ~3,760
- AKS usage: ~43 cores / ~219GB
- Platform base estimate: ~34 cores / ~175GB
- Per-VIN marginal: ~2.4mc / ~12MB → rounded to 3mc / 10MB
