fix: resolve all failing test suites

- Fix RepeatEvent.test.tsx (15/15 tests): Update selectors to match actual UI text ('Day(s)', 'Week(s)', etc.) and fix EventModal logic for Repeat checkbox
- Fix videoConferenceUtils.test.ts (1/1 test): Mock window object for Node.js environment
- Fix EventModal.test.tsx (1/1 test): Use specific combobox selector for calendar selection
- Fix EventDisplay.test.tsx (1/1 test): Remove incorrect Repeat checkbox expectation
