We should allow overriding these environment variables to ensure predictable values when running Stack Auth with Docker Compose, especially in CI/CD pipelines.

Proposed Update for docker/server/entrypoint.sh

export STACK_SEED_INTERNAL_PROJECT_PUBLISHABLE_CLIENT_KEY=${STACK_SEED_INTERNAL_PROJECT_PUBLISHABLE_CLIENT_KEY:-$(openssl rand -base64 32)}
export STACK_SEED_INTERNAL_PROJECT_SECRET_SERVER_KEY=${STACK_SEED_INTERNAL_PROJECT_SECRET_SERVER_KEY:-$(openssl rand -base64 32)}
export STACK_SEED_INTERNAL_PROJECT_SUPER_SECRET_ADMIN_KEY=${STACK_SEED_INTERNAL_PROJECT_SUPER_SECRET_ADMIN_KEY:-$(openssl rand -base64 32)}

Proposed Improvement
• Allow these environment variables to be overridden from the outside.
• Generate random values only as a fallback when no values are provided.
• This ensures predictable values in pipelines.

Looking forward to hearing your thoughts and suggestions!
