feat(transaction): return txid from submit_tx and submit_tx_bare

- Updated `submit_tx_bare` to return transaction ID (txid) as a string.
- Modified `submit_tx` to return transaction ID (txid) as a string.
- Added extraction of txid from the CLI output in `submit_tx_bare`.
- Ensured `submit_tx` captures and returns the txid from `submit_tx_bare`.
