fix(dayplan): the delete question names every date and night it changes

The question before a day goes now also says which day without a date takes over the last date, which stay running across the day loses a night and when it checks out, and what the cancelled booking costs, or that it has no expense at all; further bookings on the same stay are counted. Road trip boundaries follow their own days when the numbering still has a hole from the old delete, and ones left on no day are dropped.

A long list scrolls inside the confirm card on both shells with the buttons always in reach, Escape closes only the sheet on top and takes the trip dialog back from its review step to the form, and the panel of a deleted day closes, also when a fellow traveller deletes it. Undo steps on a deleted day are dropped, a restored place skips days that are gone, and an undo that fails says so. The day cache is written without holding up the answer once the server has it, the tip under a new start date points at the dated add button, and two Collab tests find the confirm button by its role instead of an old colour class.

 ## Shortening a trip
 
 New dates lay the days of a trip out again. Plans follow their position: the first day of the plan takes the new start date, the second the date after it, and so on. When the new dates hold fewer days than the plan, the last days go, also when it was the start that moved. Empty days without a date that are left over go as well, with any change of dates.

+Before such a save, TREK asks first: in the trip dialog as a step before the save. Editing the trip from the phone's dashboard asks in a sheet over the trip sheet instead; editing it from inside the planner shows the same step as on desktop, also on a phone. Escape in that step goes back to the form and keeps what you typed. It names the days that go, the first six by name and the rest as a count, and lists what is on them:
 
 - **Planned places** stay in the place list of the trip.
 - **Notes**, day titles and day descriptions are deleted.
-- **Bookings** on those days stay under Bookings. With **Keep bookings on their dates**, a booking whose date is still part of the trip goes back onto that day; with **Shift everything** it stays without a day. The phone does not offer the choice and keeps bookings on their dates.
-- **A stay that checks in or out on one of those days** is removed as a whole, also for nights that are still part of the trip. Unlike when you delete a single day, its booking stays under Bookings and its expense under Costs. The list shows the stay in red.

 The save button then reads **Remove days and save**. When the start moved, the same step also asks how bookings follow the new dates, as before. When the days that go hold nothing, nothing extra is asked. Should TREK fail to read the days of the trip, it warns in general terms instead of listing them. There is no undo.
