test: fix TaskItem and HistoryView test failures after refactor

Fixes test failures that occurred after the major refactoring that introduced
the shared TaskItem component. The original implementation was correct but
the tests needed updates to match the new component structure.

- Add data-testid attributes to TaskItemHeader for reliable test selection
- Update TaskItem.test.tsx assertions to use new test IDs for tokens/cache
- Fix Checkbox import path in TaskItem.tsx (ui/checkbox vs ui)
- Add missing mocks for lucide-react and Checkbox in HistoryView.test.tsx
- Update HistoryView test assertions to use correct selectors
- Ensure all 19 history component tests pass successfully

The refactoring reduced code duplication by ~250+ lines while maintaining
functionality, and these test fixes ensure the quality gates remain intact.
