This PR centralizes error handling by introducing a resilience utility using the Circuit Breaker pattern and Exponential Backoff. It specifically refactors ValuationService to use these patterns and provides a fallback strategy (Graceful Degradation) to fetch cached data when external APIs fail. Additionally, /health endpoints now validate both DB and external API availability.
Closes #37
