fix(ui): #411 — pointer swaps over inventory items unconditionally, not only in UseTarget mode

Browse source 
Corrects an incomplete reading from #411's original investigation.
UIElement_SmartBoxWrapper::FindObject @0x004E5430 calls
SmartBox::set_found_object(itemID, 0xFFFFFFFF) whenever the hovered
UI element (m_pElementLastOver) casts to UIElement_UIItem
(class 0x10000032) — UNCONDITIONALLY, not gated on target mode, and
returns WITHOUT running the 3D raycast. ClientUISystem::
UpdateCursorState @0x00564630 computes its "found" flag ONCE at the
top of the function (ebx = SmartBox::get_found_object_id() != 0,
@0x00564642) and every later branch (default/melee-missile/magic/
use/examine/use-target/busy) reads that SAME flag — so hovering an
occupied item cell shows the cursor's "...Found" variant in EVERY
mode, not only during an active UseTarget selection.

CursorFeedbackController.Update(UiRoot) already had the item-hover
special case wired from an earlier round but incorrectly gated it to
TargetMode.UseTarget only; that one-line gate is removed.
ResolveGlobalKind needed no changes at all — it already read the
snapshot's HoverTargetGuid unconditionally across every mode.

Two new tests pin the widened behavior in ordinary peace mode and in
combat mode. Live-DAT-independent (pure decomp + unit fixture).
