Add configurable cache TTL via environment variable

- IOR_CACHE_TTL environment variable to control cache duration
- Set to 0 to disable caching (always fetch fresh)
- Set to 60000 for 1 minute cache (useful during development)
- Default remains 1 hour (3600000ms)
- Improved logging to show when cache is disabled or expired
