Selection & clipboard

Cell/range selection and Excel-like copy/paste.

Cell / range selection is the foundation the clipboard builds on: enableCellSelection first, then enableClipboard for spreadsheet-style copy / paste, with enableCopyColumn / enableCopyRow as sub-toggles. Copy spans all pages (pre-pagination), and paste writes through the edit session — so it respects validation and the change-set. All opt-in.
