feat(transfer): add Claude Vision condition assessment for transfer pricing

Browse Source 
Add POST /transfer/estimate-from-photos endpoint that uses Claude Vision API
to assess furniture/appliance condition from photos, integrating with the
existing rule-based pricing engine. Includes rate limiting (5/min), image hash
caching, graceful fallback, and 17 unit tests covering all paths.
