fix: restore SSH connection timeout to 120s for 2FA authentication (#494)

The timeout was reduced from 120s to 30s in v1.10, causing 2FA login
failures. Users with keyboard-interactive authentication (TOTP/2FA)
need sufficient time to enter their verification codes before the
SSH connection times out.

Fixes #404
