fix(bridge): silence the booking_stale nudge (keep the logic, drop the message)

An orphan tap (a button from a finished/abandoned booking) still routes through stale and clears the pinned card as before, but the bridge no longer sends the "این کارت مربوط به رزرو قبلیه…" line — by request the tap is swallowed silently instead of nudging the user. Logic unchanged; only the user-facing message removed.
