Merge pull request 'test(m9): fall back to coordinate click for per-page print button (#132)' (#134) from feat/132-perpage-scroll2 into milestone/m9-monterey

Explicit stage-2 scrolls are synthesized but never move the LazyVGrid
cell's a11y frame (run 32235). If still not hittable, dump the a11y
tree and click the reported point directly — the lp argv assertion
verifies the click landed.
