Fini 419894b456 fix(canvas): keep rrect rounding for right-angle rotate previews
Previous fix flattened rx to 0 for every rotated subtree clip — but
that's only necessary at off-axis angles. At rotations that are right-
angle multiples (0°, 90°, 180°, 270° — and any 90° period), a rotated
rrect remains an rrect with w/h possibly swapped, and the AABB of the
rotated corners equals the rotated shape exactly. The rounded corner
survives the projection and should be preserved.

Compute `angleMod90 = ((angleDelta % 90) + 90) % 90` and keep the
original rx when the result is within tolerance of 0 or 90 (true
right-angle rotation). Otherwise (45°, 30°, etc) the AABB of the
rotated rrect is strictly larger than any rrect we can encode, so we
fall back to rx=0 as before.

Real-world impact: 99% of in-app rotation gestures (and any snap-to-15°
ergonomic shortcut applied to a 90° pivot point) keep the rounded
corners visible during preview instead of squaring off.
