Bug 42605: Preserve acquisition preference string values

Bug 41563 converted AcqCreateItem and UniqueItemFields to booleans when
adding them to Koha.prefs. Both preferences are strings: AcqCreateItem
controls where items are created, while UniqueItemFields contains a
pipe-separated list.

When a basket inherits AcqCreateItem=ordering, the boolean value matches
none of the receiving page branches and existing items are hidden. When
items are created on receiving, the numeric UniqueItemFields value also
fails when the page calls split().

Preserve both string values in Koha.prefs. Add a Cypress regression test
which renders orderreceive.pl and verifies the values exposed to
JavaScript.

Test plan:

Before applying the patch:

1. Set AcqCreateItem to "placing an order" and UniqueItemFields to
   "barcode".
2. Create a basket that inherits the system preference. Add an order with one
   item, close the basket, and start receiving it.
3. Confirm that the Items table has no existing item row and no Receive
   checkbox.
4. Set AcqCreateItem to "receiving an order" and open the same order for
   receiving.
5. Confirm that the Items section is empty: no item-entry fields and no Add
   item button are shown.

Apply the patch.

After applying the patch:

1. Set AcqCreateItem back to "placing an order" and open the order for
   receiving again.
2. Confirm that its existing item is listed and has a Receive checkbox.
3. Set AcqCreateItem to "receiving an order" and open the same order again.
4. Confirm that the Items section contains item-entry fields and an Add item
   button.
