• Added freescout.yaml and logofile

☑️ Self Check before Merge

• [X ] I have tested the template using the method described in README.md thoroughly
• [X ] I have ensured that I put as much default values as possible (except passwords) to ensure minimum effort required for end users to get started.
• [X ] I have ensured that I am not using the "latest" tag as this tag is dynamically changing and might break the one-click app. Use a fixed version.
• [ X] I have made sure that instructions.start and instructions.end are clear and self-explanatory.
• [ X] Icon is added as a png file to the logos directory.
• [ X] I've executed the checks if necessary by running npm ci && npm run validate_apps && npm run formatter (If failling run the prettier: npm run formatter-write)
• [ X] I will take responsibility addressing any issues that arises as a result of this PR (maintaining this app).

Thanks for the PR and apologies for the late response!

Just one minor comment.

Let's remove this as it adds little value and users cannot upgrade simply by deploying new image. This is the directory where the source code lives.
