Persist CA bundle configuration on CentOS for Nix and HTTPS tools
Move CA bundle detection from the Docker entrypoint to CentOS dependencies and persist it system-wide.
This ensures Nix, Git, curl, and Python HTTPS access works in virgin environments by configuring `/etc/profile.d` and `/etc/nix/nix.conf`.
Removes runtime-only CA exports from the container entrypoint and makes the setup reproducible and distro-correct.
