20260316h: Recipe ingredient USE popup with qty/location controls

- Clicking 'Usa' on a recipe ingredient now opens a modal popup instead of
  directly consuming. Shows location selector, quantity controls (+/- buttons),
  conf/sub-unit mode, and 'Usa TUTTO' option.
- Quantity is pre-filled with the recipe's suggested amount
- Auto-selects location with opened package
- After use, shows move-after-use modal (stays on recipe page, not dashboard)
- Separate recipe-context move functions (showRecipeMoveModal, confirmRecipeMove)
- Modal overlay z-index 250 to appear above recipe dialog
