:seedling: [backport release-0.2] Update repo CI

[sjd78]

Backport repo level CI updates following changes in #1804 and others. This will allow the "required" PR check of "unit-test" to be run on the release-0.2 branch.

Specific changes:

• Workflow ci-actions.yml replaced by ci-repo.yml
• Add ./scripts/verify_lock.mjs updated for the branch's package.json project structure
• Disable the lint step since linting does not exist on release-0.2
• Disable codecov uploads since we don't need it on an old release branch

This will also fix "hung" PR checks for any PRs to the release-0.2 branch:
