Move from schema to UI using Simulacrum conventions for adapters, actions, and RBAC.

Outline

1. Model — Add tables or models via your ORM adapter; generate migrations.
2. Data layer — Expose repository functions in lib with typed inputs.
3. Authorization — Gate mutations with RBAC helpers consistent with your template.
4. Server Actions — Validate with Zod, call repositories, return structured errors.
5. UI — Build components with TanStack Query hooks for reads.
6. Tests — Add Playwright coverage for the critical path (E2E).
