fix(build): match project_7 proven Dockerfile — remove ENV lines + .dockerignore

project_7 docker build succeeds on competition platform.
Diff was: 5 ENV lines + .dockerignore whitelist.

ENV lines may override base image paths or trigger patch_ops.sh failures.
.dockerignore whitelist may exclude files the build needs.

Now Dockerfile is byte-identical to project_7.

// Base image has ixformer::infer namespace with 14 functions.
