Improve Tests & Checkout Experience

♻️ Current situation & Problem

• The current tests make a lot of assumptions about the text on-screen in the template application which makes it hard to modify this for the individual use cases.
• The repository currently uses git lfs to store image files.

💡 Proposed solution

• This PR improves the UI tests by focusing less on the content and more on the core user flow
• Moves all files out of LFS storage
