ohos: Avoid mouse move exactly on item edge in tst_cursor

controls() and pageIndicator() moved the mouse to the exact (0, 0)
edge of the control under test. QQuickItem::contains() treats bounds
as (x >= 0 && x < width), so a position of QPoint(0, 0) has no margin
for error.

On platforms with a non-integer device pixel ratio (e.g. OHOS, DPR 1.9)
such a position is not delivered exactly. QTest::mouseMove() passes
device-independent coordinates, qt_handleMouseEvent() converts them to
native coordinates, and QWindowSystemInterface::handleMouseEvent()
converts them back by multiplying with scale factor (1/sf). For this
scale factor that round trip is not an exact inverse, so a move
requested at exactly (0, 0) can be delivered a fraction outside the
item.

Move the probe points from (0, 0) to (1, 1), so that the mouse
position lands on the control regardless of the sub-pixel rounding
error.

Fixes: QTBUG-150331
