Setup vitest and playwright testing

[tylercchase]

Summary

• Updates angular to use the vitest testing framework for component testing.
• Updates our e2e testing library to playwright, as well as adding some initial example tests for documentation of how to use playwright. Converting our test suite to playwright will be part of a larger effort. As part of the example, setup an authentication workflow so that we can have tests that use features that require user profiles.
  • For now I'm wanting to focus more on getting items converted from our previous testing solution via the test generator, and then finding wins for optimizing / making tests more resilient when we have more tests in our codebase.
• Setup Github actions for both playwright and vitest
  • I want to revisit these in the future to setup testing multiple operating systems at once, but that will require a separate effort

Tests & Build

• npm run lint passes
• npm test passes
• ng e2e passes
• npm run build succeeds

Notes

• This also gets rid of some of the old stuff that was living around the e2e folder from back at the start of the project.
