feat: add RemoveBrokers tRPC router, service layer, broker registry, and removal engine

- Create Valibot schemas for removal request CRUD, scan, and listing filters
- Implement broker registry with 48 major data brokers and removal metadata
- Build removal engine with automated, form, email, and status tracking support
- Add service layer with subscription-scoped operations: create/get/scan/stats/process
- Wire removebrokers router into root app router
- Write 20 passing unit tests (router + service layer)
