feat: add blockchain state and balance endpoints with multi-chain support

Browse Source 
- Add GET /state endpoint to blockchain RPC router for chain state information
- Add GET /rpc/getBalance/{address} endpoint for account balance queries
- Add GET /rpc/head endpoint to retrieve current chain head block
- Add GET /rpc/transactions endpoint for latest transaction listing
- Add chain-specific wallet balance endpoint to wallet daemon
- Add blockchain state CLI command with --all-chains flag for multi-chain queries
