/**
 * Tests for UserFormDialog Component
 * Verifies component exports and hook integration
 * Note: Complex form validation and Dialog interactions are tested in E2E tests (admin-users.spec.ts)
 *
 * This component uses react-hook-form with Radix UI Dialog which has limitations in JSDOM.
 * Full interaction testing is deferred to E2E tests for better coverage and reliability.
