Siavash Sameni d27e85ecf2 feat: SAS (Short Authentication String) for call identity verification ...

Derive a 4-digit code from the shared DH secret via HKDF with label
"warzone-sas-code". Both peers compute the same code; a MITM relay
produces a different one. Users compare verbally during the call.

- CryptoSession::sas_code() -> Option<u32> on the trait
- ChaChaSession stores and returns the SAS
- HKDF derivation in WarzoneKeyExchange::derive_session()
- Tests: both peers match, MITM produces different code
