move_selection() only clamped at 0, letting the row/col index go past
the last valid item. Selected_cell_key() would then return None, leaving
the cursor in a phantom position with no selectable cell.
Now clamp both row and col against the actual item count so pressing
Enter on the last row keeps the cursor on that row.

N (from anywhere) or n (in Category panel) opens an inline prompt
to add categories one after another without typing :add-cat each time.
- Yellow border + prompt distinguishes it from item-add (green)
- Enter / Tab adds the category and clears the buffer, staying open
- Esc returns to the category list
- Cursor automatically moves to the newly added category
