The stay picker disabled only occupied nights when choosing a check-in, so
a free day with an occupied night closer than min_nights was still
selectable — e.g. min 2 nights with the night after next booked. Picking it
left every later day disabled (no legal check-out), so reka's only move was
an earlier day, which it silently swapped into the range: the guest picks a
date and the calendar 'jumps backwards'. Disable such a day up front: a
check-in is valid only if the minimum stay fits before the next occupied
night and within the loaded window.
