Refactor add meal flow and remove v2 routes

Migrated add_meal_v2 routes and templates to add_meal, renaming endpoints and updating references throughout the app. Removed legacy daily_log2 route and template, consolidating to daily_log. Moved macro_arr_to_json to utils.py for reuse. Updated navigation and redirect logic to use new routes. Improved item finding and barcode scanning UI.
