Adds 'show-password' subcommand to the muxplex CLI that: - Prints 'Auth mode: PAM — no password file used' when MUXPLEX_AUTH is not 'password' and PAM is available - Prints 'Password: <pw>' when a password file exists - Prints guidance to auto-generate when no password file found Also imports load_password and pam_available at module level in cli.py to enable testable patching via muxplex.cli namespace. Tests added: - test_show_password_prints_password_from_file - test_show_password_no_file - test_show_password_pam_mode
