- app.rs: scroll_rows (Ctrl+D/U) now clamps to the cross-product row count and follows the viewport, matching move_selection's behaviour. Previously it could push selected past the last row, causing selected_cell_key to return None and silently ignoring edits. - model.rs: add normalize_view_state() which resets row/col offsets to zero on all views. - main.rs, dispatch.rs, app.rs: call normalize_view_state() after every model replacement (initial load, :Load command, wizard import) so stale offsets from a previous session can't hide the grid. - app.rs: clamp formula_cursor to the current formula list length at the top of handle_formula_panel_key so a model reload with fewer formulas can't leave the cursor pointing past the end.
