feat: migrate wallet daemon and CLI to use centralized aitbc package utilities

- Migrate simple_daemon.py from mock data to real keystore and blockchain RPC integration
- Add httpx for async HTTP client in wallet daemon
- Implement real wallet listing from keystore directory
- Implement blockchain balance queries via RPC
- Update CLI to use aitbc.AITBCHTTPClient instead of requests
- Add aitbc imports: constants, http_client, exceptions, logging, paths, validation
- Add address and amount validation in
