feat(collections): Expand curated categories and improve tier modal UX

- Add 3 new curated categories: DIY & Repair, Agriculture & Food, Computing & Technology
- Reorganize content logically (moved DIY/food content from Survival to appropriate new categories)
- Update tier selection modal to show only each tier's own resources
- Add "(plus everything in X)" text for inherited tier content
- Reduces visual redundancy and makes tiers easier to compare
