refactor(command): improve axis operation feedback

Improve feedback for axis operations:

- `CycleAxisAtCursor` : Now provides a status message if no category is at
  the cursor.
- `TileAxisOp` :
    - Now provides a status message showing the new axis (e.g., "Category →
      Row").
    - No longer automatically switches to `AppMode::Normal` , allowing for
      multiple consecutive adjustments.
    - Provides a status message if no category is at the cursor.
