[Task](ci): Automate Environment Variable and appProps.JSON Creation for Docker Images

[ArtieReus]

Task Description
Enhance the Docker image build process by automating the creation of environment variables and the appProps.json file using appProps.template.json as the source of truth. Currently, every change to an app property requires manual updates in appProps.template.json, README.md, Dockerfile, and entrypoint.sh.

Sub-tasks

• Automate Environment Variable Creation
  • Avoid manually defining environment variables in Docker images.
  • Use appProps.template.json as the source to dynamically create environment variables during the build or runtime process.
• Automate appProps.JSON Creation
  • Eliminate hardcoded values for generating the appProps.json file.
  • Automate its creation using appProps.template.json to ensure consistency and reduce manual errors.
• Generalize and Reuse entrypoint.sh
  • Refactor entrypoint.sh to support the automation process, making it more generalized and reusable across different applications.
