fix(pdf): include multi-day transport return/arrival in PDF itinerary (#847)

Reservations were matched to days by pickup date only, so the end-day
card (e.g. car Return, flight Arrival) was silently dropped from the PDF.
Add span-aware helpers mirroring DayPlanSidebar logic: match by day_id/end_day_id
span, show reservation_end_time on end days, prefix title with phase label
(Return/Arrival/etc.), and use per-day position for sort order.
