fix: add TTY handling to transactions commands and improve genesis info

- Added sys.stdin.isatty() check before getpass in transactions send and batch commands
- Added environment variable fallback (AITBC_WALLET_PASSWORD) for non-interactive environments
- Added --data-dir option to genesis info command to allow custom data directory paths
- Improved error messages in genesis info to show chain_id and data directory
- Fixes termios.error in non-interactive environments for transactions
