Bug 42997: Warn staff when a due date override runs into the next booking
When checking out a booked item, staff may override the suggested due
date. If that override runs into the next booking for the item, the
previous patch would silently keep the booking's original end date -
staff had no way of knowing their override crossed another booking.

This patch adds an exclude_booking_id option to Koha::Item->find_booking
so a lookup can skip a specific booking (here: the patron's own booking
being collected), and uses it in CanBookBeIssued to detect when an
explicitly requested due date would run into the next booking for the
item. When it would, a new BOOKED_DUE_DATE_CLASH confirmation is raised
and displayed on the checkout screen, telling staff the linked booking
will keep its original end date if they continue.

Only explicitly requested due dates trigger the confirmation -
calculated due dates are clamped to the booking end date later in the
staff checkout flow, so checking them would produce false positives.
SIP is unaffected as it never passes a requested due date.

Test plan:
1) Run t/db_dependent/Circulation.t and t/db_dependent/Koha/Item.t
2) Create two consecutive bookings on the same item for two patrons
3) Check the item out to the first patron specifying a due date beyond
   the second booking's start date; confirm the new confirmation
   message appears and checkout only proceeds once confirmed
