Fix Badge Magic PR CI Screenshot Builds

[mariobehling]

The Badge Magic app repository currently has broken screenshot builds in the CI pipeline for pull requests. This prevents proper verification of UI changes and makes it harder to review PRs that affect layouts, themes, or other visual components.

Expected Behavior

• CI should automatically generate and upload screenshots for PR builds.
• Reviewers should be able to view the updated screenshots directly in the PR.

Current Behavior

• Screenshot build step fails in CI jobs for PRs.
