#14074 CellFilters: Notify filter facade from all property-filter mutations

The view filter nodes were unified under a read-only RimFilterInViewCollection
facade, and the source collections are now tree-hidden. As a result, the
existing collection->updateConnectedEditors() calls no longer refresh the tree:
the filters are shown under the facade, which only refreshes when a source emits
filtersChanged/wrappersChanged.

Several property-filter mutations changed the child array without emitting that
signal (insertAt/push_back/erase do not auto-fire onChildAdded/onChildDeleted),
so newly created or removed filters did not appear under the Filters node:
property filter insert, new combined filter, add linked filter, undo of a
property-filter creation, and Show Contributing Wells.

Emit the change signal from these paths (via the existing onChildAdded hook, or
filtersChanged on removal) so the single facade handler refreshes the tree. The
cell-filter, paste, property-add and data-filter paths already emit the signal
and are unchanged.
