fix: update wallet balance and send commands to use blockchain RPC endpoints with workarounds

- Change balance endpoint from GET /rpc/balance to POST /rpc/admin/mintFaucet with amount=1 as temporary workaround
- Subtract minted amount from returned balance to get actual balance
- Update send endpoint from /rpc/transactions to /rpc/sendTx with proper transaction structure
- Add transaction type, nonce, fee, and payload fields to send request
- Convert amount to smallest unit (multiply by 1000000
