chore: migrate to vitest

[cgdibble]

This does a lot.

• sets up for use of vitest in the repo
• remove Kraken testing libs, mocha, jest, and karma
• adopts idiomatic vitest patterns of mocking and assertions
• removes cases of test-aware implementations (some still linger on, I addressed as I ran in to them with fixing tests)
• removes logger tests that really test beaver logger internals
• removes more complicated mock script util that had it's own test suite
• merge script and scriptUtils tests since those were all tests of script.js
• uses vitests coverage as well. Dumps all coverage in to a single coverage dir since it's no longer split between test runners. Merges coverage uploading to a single GH Action step, too.
• removes old test tool files and references from package.json scripts
• co-locates test files with implementation and ditches the ./test dir entirely

This spawned from a need to test recent fraudnet changes. So be mindful that this base branch is to our fraudnet feature branch, and that we still need to add tests for fraudnet so that is still pending.

Note: Initially done here in #117 but that was using a feature branch as the base branch. This just moves the same changes to PR against main.
