Update grid widget with adaptive column/row widths and pruning support. Replaced fixed ROW_HEADER_WIDTH (16) and COL_WIDTH (10) with adaptive widths based on content. MIN_COL_WIDTH=5, MAX_COL_WIDTH=32. MIN_ROW_HEADER_W=4, MAX_ROW_HEADER_W=24. Column widths measured from header labels and cell content (pivot mode measures formatted values, records mode measures raw values). Row header widths measured from widest label at each level. Added underlining for columns sharing ancestor groups with selected column. Updated is_aggregated check to filter virtual categories.
