 * Order Detail Item — Inline Modification Controls
 *
 * When order status is 'active' (canModify = true), each item row shows:
 *   - Item name
 *   - Qty controls: [-] qty [+]
 *   - Line price
 *   - Actions: note toggle icon + remove [X]
 *
 * When the item is being saved (isSavingItem matches), the row reduces
 * opacity to provide subtle loading feedback without a spinner.
 *
 * Design reference: Section 4.3.5
 * Requirements: 5.2 AC-4, 5.2 AC-6
