improve tests for vitest by fully utilizing testing lib api

[chris-czopp]

• changed tests to utilize more of the testing library API, things like: expect(screen.getByRole('checkbox')).not.toBeChecked();
• upgraded vitest template modules
• added .idea/ to .gitignore

In the future I'd like to add API mocking too.

Hey, sorry for the delay it took me to evaluate this MR, life's been in the way... I reckon I don't know that much about vitest and all the testing framework. Would you mind pulling the latest changes in the repo and adapting your MR to it? 🙏🏻
