/**
 * End-to-End Test: Complete NFT Tool Chain Entity Persistence Flow
 *
 * This script validates the complete flow:
 * 1. Create "Forever" NFT collection (real Hedera testnet)
 * 2. Inscribe "Forever #1" image (real inscription)
 * 3. Test "mint Forever #1 onto token" (real minting with proper entity resolution)
 * 4. Verify Topic ID "0.0.6624888" → "hcs://1/0.0.6624888" conversion
 *
 * NO MOCKING - tests actual service integration with real network operations
