feat: editable AI draft card — edit food/macros before adding (#16)

- FitnessDraft properties changed from let to var (mutable)
- New EditableDraftCard with Edit/Done toggle:
  - Editable food name
  - Editable macros (calories, protein, carbs, fat, sugar, fiber)
  - Meal type picker (dropdown menu)
  - Editable quantity
- Edited values flow through draftToDict → apply endpoint
- No backend changes needed — purely iOS UI
- Default view is read-only (same as before), tap Edit to modify
