feat: enhance Vue component tests with comprehensive DOM and API testing

- Remove empty.spec.ts and replace with individual component test files
- Add comprehensive tests for DockviewVue, SplitviewVue, GridviewVue, and PaneviewVue components
- Test actual dockview-core integration without mocking core functionality
- Add Vue component instantiation and lifecycle testing
- Test DOM rendering, API validation, and framework integration
- Add utility function tests for VuePart, findComponent, and mountVueComponent
- Increase test coverage from ~20 basic tests to 52 comprehensive tests
- Validate Vue-specific component creation and property handling
- Test component disposal, updates, and error handling scenarios
