SlotCenterPoint validates minimum width incorrectly

[jwagenet]

SlotCenterPoint raises ValueError: Slots must have width > height. Got: {height=} width={half_line.length * 2} (computed) when the slot width is too small, however the minimum width calculation is incorrect. Also, the fstring was broken by the formatter.

The minimum width should actually be half_line.length * 2 + height or validated as half_line.length > 0 or center != point.

Example

SlotCenterPoint((0, 0), (1.5, 0), 3) but this would actually produce a slot with overall length 6.

Unrelated, but I think it's weird/inconsistent this object takes a center point at all and isn't centered on the origin like all other sketch objects (except Polygon) when unlocated.
