Plan B for the punch UI: don't just grey out file transfer — hide it entirely when the connection is relay. The user can't try to use it, and we save the toast explanation. When punch succeeds (P2P, direct), the menu items reappear. Applied to: - Transfer file - TCP tunneling (Leaving View camera and Terminal in the menu regardless of mode — they don't use server bandwidth significantly.)
