test(frontend): add component tests — TimeEntryForm, WeeklyView, App smoke

- TimeEntryForm.test.tsx: fills date/project/h:mm, clicks submit, asserts fetch called with correct JSON body (mocked fetch) - WeeklyView.test.tsx: renders with stubbed WeeklyReport fixture, asserts each day's h:mm and the week total display correctly - App.test.tsx: smoke test — renders layout with TopBar and main content Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
