Update test run page & replace renderer's iframe

[howard-e]

This aims to update the Test Run page's functionality to bring it up to date with our current backend implementation.

Before merge checklist:

• Merge Add harness input/output  aria-at#466
• Merge Allow import-tests to account for both the old and new build structure when importing from aria-at #309

Recommended Setup Script

if [[ "$OSTYPE" == "darwin"* ]]; then
    createdb # run this if the PostgreSQL installation is freshly installed
    yarn db-init:dev;
else
    sudo -u postgres yarn db-init:dev;
fi;

yarn sequelize db:migrate;
yarn sequelize db:seed:all;
yarn workspace server db-import-tests:dev;

The major feature addition here is that the iframe which would previously hold the test content is now built and ran locally and depends on w3c/aria-at#466.

Known Issues

• Focus is lost after closing Test Window - to be addressed

We should pick a style for buttons and then stick with it e.g. title case or just initial caps?

I'm confused about "My Issue is not in this list". I think the only two logical possibilities are "My Issue Is Not In This List" or "My issue is not in this list". I don't understand the caps on both "My" and "Issue".

Title case for buttons seems very logical IMHO, so that would be my vote.

This is aweeesome, can't wait to merge it.

I'm curious about the aria-at-harness.mjs, aria-at-test-io-format.mjs and the other files in this resources folder - I think I sort of recognize them from the ARIA-AT repo? Are they copied here? Is that permanent? Or are they meant to stay?

No real notes besides that question, I should be able to approve pretty soon after you feel like the blockers are clear.

Agreed. Title Case v Sentence case is a decision to be made.

This isn't permanent. This was mainly for ease of debugging purposes.

@alflennik @jesdaigle, this is now ready for your review.

Having tested this thoroughly on the sandbox, staging, etc., and using it as the base for my current branch, I can safely say this is ready for merge, and it's fantastic stuff!
