Suggestion - Add regression testing

[TwoAbove]

Noitool is growing, and I'm wasting enough time to warrant automatic e2e testing of the UI.

Use Cypress and create automated tests for:

• [x] General UI
• [x] Correct seed info generation
• [ ] Settings
• [ ] Favorites
• [ ] Seed query generation

Anything else?

Also, add these tests to GitHub actions.
