Tie alerts: no map, body tap doesn't direct

A tied-cheapest notification now delivers immediately with the choice
buttons and NO map snapshot (a map would only show one arbitrary
station). Tapping the notification body of a tie no longer opens
directions — nothing has been chosen; only the option buttons trigger
directions. Single-station alerts keep the embedded map + tap-to-route.
