Update from Copier template v0.4.0

- Accept RBAC system: user_roles table, role_required decorator, grant_role/revoke_role/ensure_admin_role functions
- Accept improved billing architecture: billing_customers table separation, provider-agnostic naming
- Accept enhanced user loading with subscription/roles eager loading in app.py
- Accept improved email templates with branded styling
- Accept new infrastructure: migration tracking, transaction logging, A/B testing
- Accept template improvements: Resend SDK, Tailwind build stage, UMAMI analytics config
- Keep beanflows-specific configs: BASE_URL 5001, coffee PLAN_FEATURES/PLAN_LIMITS
- Keep beanflows analytics integration and DuckDB health check
- Add new test files and utility scripts from template
