test: enhance test configurations and cleanup procedures

Updated the Vitest configuration to increase test and hook timeouts to 20 seconds, addressing flaky tests under pre-push load. Additionally, improved test cleanup procedures across multiple test files by ensuring mocks are cleared after each test, enhancing test reliability and maintainability.
