feat(planner): show variety score in swap menu via RecipePicker

Replace SwapSuggestionList with RecipePicker in both mobile and desktop
swap contexts. RecipePicker now accepts excludeRecipeId, replacingRecipe,
and isDisabled props. Mobile swap sheet also triggers suggestion fetch
via activePickerDate so green/yellow/red score badges appear during swap.
