Add Shopping tab combining Trello and PlanToEat lists

- New Shopping tab aggregates items from Trello Shopping board and PlanToEat
- Items grouped by store, then by category (for PlanToEat)
- Trello list names treated as store names
- Replace PlanToEat meals API with web scraping (uses session cookie)
- Add error logging for PlanToEat fetch operations
- Recipe links now point to cooking view (/recipes/{id}/cook/{event_id})
