Docker Repair | Remove ubuntu user to replace with crafty user

What does this MR do and why?

This Merge Request removes the default ubuntu user (UID 1000) from our Ubuntu 24.04 base image and to use our custom non-root user (crafty) with the correct UID and permissions.

• Why? In Ubuntu 24.04, a default ubuntu user is created with UID 1000, which conflicts with our existing user creation process. This conflict prevented existing containers from accessing mounted files, causing a boot loop. By removing the shipped user and continuing to create our own, we ensure consistent UID assignments and restore functionality for both fresh and existing containers.

No UI changes; this MR affects container initialization and user permissions only.

How to set up and validate locally

1. Pull the MR branch:

   git fetch
   git checkout devops/docker-image-user-repair

2. Build the Docker image:

   cd docker
   docker compose up --build

3. Verify container logs:
   • Ensure there are no permission errors or unexpected boot loops.

Once you confirm that the container starts and operates without permission issues, the fix is validated.
