Add three new methods to GridElement for efficient grid cell extraction: - dumpVisibleCells(): dumps currently visible cells in one browser round-trip - dumpAllCells(): dumps all grid cells by scrolling through pages - dumpCells(fromRow, toRow): dumps cells for a specific row range This addresses the performance issue when testing grid content, reducing browser round-trips from N×M (one per cell) to 1-50 requests depending on grid size, resulting in 20-500x performance improvement. Only visible columns are included in the output. Hidden columns are filtered out automatically. Fixes #1876
