Update deepCopy, hasOwn, emotion, and config files

[JakeWags]

Updates deepCopy documentation to reflect actual usage.

Update structuredClone usage in project to use version-safe deepCopy.

Update instances of Object.hasOwn to prototype version for esnext typescript versioning issues. May be resolved with typescript config changes, however.

Remove extraneous emotion jsx compiler statements (this is included in the tsconfig)

Update configuration files (package.json, tsconfig, vite config) to resolve install-time errors in other environments.
