 filas con cambios pendientes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Añadido dirty_row_id: ?i64 a DrawRowsConfig
- drawRowsWithDataSource aplica blendColor(state_modified, 0.25) si dirty
- VirtualAdvancedTable pasa row_edit_buffer.row_id cuando has_changes
