fix: relocate Docker entrypoint to scripts/docker/

[wambitz]

Summary

Move the Docker entrypoint script(s) to the scripts/docker/ directory for better project organization.

Details

• Currently, the entrypoint script is not located under scripts/docker/, which makes the structure less clear and less maintainable in the long run.
• Relocating entrypoints into scripts/docker/ is a common best practice and helps keep project root clean while grouping Docker-related scripts together.
• No logic change—just a git mv and the appropriate path adjustments in Dockerfile and other references (CI/CD, documentation, etc).

Steps

1. Move the entrypoint script(s) to scripts/docker/.
2. Update all relevant references, such as in your Dockerfile (the ENTRYPOINT or CMD line), and any documentation or CI files that use the script.
3. Test docker build to ensure the entrypoint works from the new location.

This is a minimal refactoring task. If you want further improvements—like consolidating multiple docker scripts, adding ownership comments, or making the script shellcheck-compliant—open follow-up issues or let me know.
