Increase test timeouts for better coverage

- Test timeout: 60s → 90s (for slow accounting pages)
- Expect timeout: 20s → 30s (for dynamic content)
- Navigation timeout: 45s → 60s (consistency)
- fullyParallel: false (avoid resource conflicts)

This should help ~10-20 more tests pass that were timing out
at 60s but complete at 70-80s.
