re #27319

An argument was missing from a refactored function

Re #26533

Also includes some minor refactoring of tests which require an
instrument to be set to construct the instrument directly in the test
rather than call a notification function which causes the instrument to
be loaded from the name.

Coordinate via the main window to disable the instrument drop-down box
on all Batch tabs if any batch is processing or autoprocessing.

Re #26536

Make these clearer that they are notify functions

Re #26536

Re #26536

Use clearer names to indicate a notification of a request, a function that performs the action, and a notification
of a result from that action.

Re #26536

This is no longer necessary now that the instrument is stored in and set
by the main window

Re #26536

Setting initial state is done by the main window after adding a new
batch is complete and all presenters know their parent presenter. Move
the initialisation of the instrument list to the same place.

Re #26536

The instrument has been moved to the main window so that it can be
synchronised between batches

Re #26536

Update invalid include path. Add missing updates to new files (new
include file and new namespace).

Re #26498

Add an interface to the BatchPresenterFactory.
