Philipinho 137c02a10f feat(base): sticky table header so columns stay visible while scrolling
Pins the header row to the top of the gridWrapper scroll viewport, with
the pinned-left corner cell stacking above pinned body cells at the
top-left intersection. The trailing add-column button gets the same
sticky treatment so it doesn't drift away from the row.

Subtle bit: `position: sticky` confines an element to its containing
block. The previous subgrid `.headerRow` wrapper was 34px tall, so
sticky cells could only travel 34px before scrolling out with the
wrapper. Switching the wrapper to `display: contents` lets the cells
become direct grid children of `.grid` (full table height) so sticky
travel matches the scroll range. role="row" survives display:contents
in modern browsers.
