* test(editor): cover the drawShape (snap-to-shape) tool

The drawShape tool had no dedicated tests, which let master's toolbar /
active-tool rewrite silently break it during the merge: actionFinalize
reverted to the selection tool after every sketch, because the drawShape
flow finalizes without a `newElement` and so failed master's new
`&& element` guard.

Covers the behavior the merge had to preserve:
- sketch recognition (rectangle, ellipse) and the too-small no-op
- the tool stays active after finalizing, so shapes can be sketched
  consecutively (regression guard for the above)
- activation via the S shortcut and the extra-tools dropdown
- the tool's own cursor

Points are fed into the trail directly rather than through pointermove,
which is rAF-throttled and would drop all but one point per frame — the
same approach lasso.test.tsx uses.
