Bug fixes and review screen

• You can now add multiple ingredients when using Quick Add for recipes

• Added a Quick Add button to the Shopping List for faster item entry

• Fixed an issue where the Quick Add and Filters sheets were not displaying correctly

• Fixed the keyboard covering input fields on the Quick Add, Filters, and Choose Recipe sheets

• Fixed day names showing incorrectly on the Plan screen

• Fixed the Current Week button not scrolling to the right week

• The week controls bar now stays pinned to the top as you scroll through the week

• Clearing a week now asks for confirmation before removing your meals

- Quick Add sheet for the Shopping List — tap the add button to quickly add items by name with auto-detected category
- Fixed Quick Add sheet layout — the card was incorrectly positioned off-screen and the Add Recipe button was outside the card bounds
- Fixed Filters sheet layout — same positioning issue, also removed excessive padding
- Keyboard no longer covers inputs on the Quick Add, Filters, and Choose Recipe for Day sheets — all three now lift above the keyboard when an input is focused
- All sheets are now properly constrained in height so the dark backdrop is visible behind them, and content scrolls if needed
