RDT-Client Configuration Validator

This script verifies that RDT-Client is properly configured and integrated
with Surge services. It checks:

1. RDT-Client service availability
2. Real-Debrid token configuration
3. Torrentio indexer in Prowlarr
4. Download client setup in Radarr/Sonarr
5. End-to-end connectivity

Usage:
