fix(planner): an untimed hotel bookend only closes a local day-trip loop (#2157)

Without stay times the bookend leg drew unless a carrier or a 2000 km edge stop disproved it, which is exactly the reported car trip: home five hundred kilometres away, routed back to the hotel after check-out. The disproof threshold is a day-trip distance now, and the route optimizer anchors through the same rule on desktop and mobile instead of unconditionally, so drawing and optimizing agree.
