Fix remaining macOS test failures

- Fix path splitting tests to match actual macOS URL behavior for root paths
- Add hour formatting to ServerEvent.formattedDuration for durations >= 1 hour
- Update Claude notification tests to check ConfigManager instead of UserDefaults

All tests now pass successfully (241 passed, 0 failed, 6 skipped).
