chore(deps): bump vitest to v4 and fix tests

[jescalada]

Description

Bumps Vitest to v4 and fixes resulting failing tests from syntax changes.

Despite adding the uiPort mocks to fix some EADDRINUSE errors when running tests in parallel, I decided to keep the sequential tests (by disabling the fileParallelism option, formerly poolOptions.forks.singleFork).

This is because a few tests still fail when running npm run test-shuffle, and the MongoDB integration tests also fail on the CI when enabling parallelism. I made an issue to track this so we can benefit from parallel test execution speedup: #1565

The dependency review is complaining on npm/yauzl v3 which apparently does have an MIT license: https://www.npmjs.com/package/yauzl

This is a known issue with Dependency Review not falling back to the GH license fetch API when the dependency graph API doesn't fetch as intended: actions/dependency-review-action#704
