fix(reservations): show day date range on accommodation cards

Hotel reservations store their date range in day_accommodations rather
than on reservation_time, so the card date block never rendered. Pull
accommodation_start_day_id / accommodation_end_day_id from the SQL join
and surface them on the card.

Also apply Maurice's badge-pill pattern (day name + localized date pill)
to the day-range display, consistent with the modal day selectors.
