refactor(platform): migrate Tenant to anemia model, use Manager pattern

- Convert Tenant to anemia model with long Id (no strong-typed ID)
- Add ApplicationUser, ApplicationRole to Platform.Domain (inherit Identity)
- Add TenantInfo value object for user-tenant redundancy
- Implement TenantManager/TenantStore in Platform.Infrastructure
- Update PlatformDbContext to inherit IdentityDbContext
- Migrate AuthService and Console to use Platform entities
- Remove old TenantRepository (replaced by TenantManager)
- Update AGENTS.md documentation
