Add editable notes field to ingredients in the unified recipe editor, allowing users to add preparation notes like "sifted", "room temperature", etc.
Changes:
- Added notes input field below amount/unit/name inputs in UnifiedEditRecipe.tsx
- Styled notes field with italic, gray text to indicate optional nature
- Added placeholder text with examples (e.g., sifted, room temperature)
- Field uses existing ingredient.notes field from database schema
- Notes are saved with other ingredient data via updateIngredient function
The notes field is displayed with reduced font size and lighter styling to differentiate from required ingredient fields.
