Rewrites scrollSpreadsheetToCell with fixes for multiple issues discovered
during E2E testing:
- Use Playwright boundingBox (page-level coords) instead of frame-internal
getBoundingClientRect for visibility checks — frame's clientWidth is wider
than the actual visible iframe area clipped by parent elements
- Use iframe element's boundingBox to determine visible region — cells behind
the section panel (x < iframeBox.x) were incorrectly considered "visible"
and focus clicks hit the section panel instead of the spreadsheet
- Use div[y]+div[x] attribute selectors instead of div.RxCy CSS classes —
the RxCy class numbering differs from y/x attribute values
- Accept cellLoc parameter from caller instead of re-searching — avoids
selector mismatch and handles cells missing from some rows
- Native click through mxlCurrBody overlay (page.mouse.click) for focus —
frame.locator().click() bypasses overlay causing header/data desync,
page.mouse.click() + frameEl.focus() doesn't transfer keyboard focus
- Pick rightmost/leftmost fully-visible cell for focus based on scroll
direction — each arrow press immediately triggers platform scroll
