fix: standardize container name and image references in compose files

[zbejas]

This pull request updates the Docker Compose configuration files to standardize naming conventions and correct file references. The main focus is on ensuring consistency between the compose files and aligning with best practices for container and image naming.

Configuration and Naming Consistency:

• Changed the container_name from ad-fontem to ad_fontem in both compose.yml and compose.build.yml to use underscores instead of hyphens, ensuring consistent naming. [1] [2]
• Updated the image name from zbejas/ad-fontem:latest to zbejas/ad_fontem:latest in compose.yml for consistency with the new naming convention.
• Fixed the env_file reference in compose.yml by removing the unnecessary fileName: key and using the correct format.
