fix(print): route wall mid-handle pointerdown through place-feature path

The drag-to-translate mid-handle (T054) was added on top of the
segment-hit line and stole every pointerdown at the centre of a wall,
so "Add window/door/closet" → click-near-centre dropped no feature.

Now the mid-handle's pointerdown checks pendingFeatureType first and
defers to the place-feature path when armed; only when no feature is
armed does it start a drag.

Adds a regression test that dispatches pointerdown directly on the
mid-handle (where the bug actually lived) for all three feature types.
