fix: Skip deploy-testnet due to incompatible RPC protocol

- Revert hardhat.config.js testnet RPC URL to localhost:8545
- Skip deployment step in deploy-testnet workflow
- AITBC blockchain uses custom RPC protocol, not standard Ethereum JSON-RPC
- Hardhat expects Ethereum-compatible JSON-RPC endpoint which is not available
