Add comprehensive test categories for Vue component lifecycle and behavior
- Add lifecycle testing utilities for mounting, unmounting, and prop updates - Add computed property testing for values, dependencies, and caching - Add watcher testing for triggers, cleanup, and deep watchers - Add event modifier testing for .prevent, .stop, .once, and .self - Update test utilities to be Vue 3 compatible with proxy system - Apply new test categories to RegistrationNotice and LargeIdenticonModal - Increase total test count from 149 to 175 tests with 100% pass rate - Establish standardized patterns for comprehensive component testing New test categories: - Component Lifecycle Testing (mounting, unmounting, prop updates) - Computed Property Testing (values, dependencies, caching) - Watcher Testing (triggers, cleanup, deep watchers) - Event Modifier Testing (.prevent, .stop, .once, .self) Files changed: - src/test/utils/testHelpers.ts (enhanced with new utilities) - src/test/RegistrationNotice.test.ts (added 4 new test categories) - src/test/LargeIdenticonModal.test.ts (added 4 new test categories)
