Relates to #223

Scope

Replace NHTSA client usage in the vehicles controller and service with the OCR proxy, and update cache logic.

Changes

Replace NHTSAClient with OcrClient in vehicles.controller.ts
Move VIN validation (regex) into controller (was in NHTSAClient)
Move cache logic (getCached/saveToCache) from NHTSAClient into vehicles service or controller
Refactor mapNHTSAResponse() to mapVinDecodeResponse() - takes Gemini response, does dropdown matching
Update vin_cache raw_data to store Gemini response format
Add migration 007_truncate_vin_cache.sql to clear stale NHTSA-format cache entries
Update error messages from NHTSA references to OCR service references

Acceptance Criteria

POST /api/vehicles/decode-vin routes through OCR service
VIN cache works with Gemini response format
Dropdown matching (year/make/model/trim/engine/transmission) preserved
Tier gating unchanged (Pro/Enterprise)
Error handling for OCR service failures
