fix(tests): reduce default test timeout when Percy is disabled

[rohitpaulk]

Decrease QUnit test timeout from 5000ms to 3000ms for cases
when Percy is not enabled. This speeds up test runs by avoiding
unnecessary wait time while maintaining sufficient timeout for
test stability.

---

Note

Reduces default QUnit timeout to speed up local/CI tests without Percy.

• In tests/test-helper.js, updates QUnit.config.testTimeout to config.x.percyIsEnabled ? 20000 : 3000 (from 5000).
