feat: Add IP_RANGES_FETCH_ENABLED environment variable

Browse Source 
This change adds a new environment variable to control whether IP ranges
are fetched during application startup. When set to 'false', the initial
fetch will be skipped, which can:

1. Speed up application startup
2. Avoid connectivity issues in environments with restricted internet access
3. Prevent startup failures when CloudFront or CloudFlare services are unreachable
