Tests: Vitest configuration cleanup (#5888)

## Summary

Simplify default scripts. Filtering is still available to users, we can
revisit tagging or grouping later.
This fixes the issue where we had tests that were in the codebase but
never run because they weren't under `/src/components`

Also deletes the duplicate litegraph tests and their associated vitest
config file.

## Changes

- **What**: Test cleanup

## Review Focus
