catborise 7435d66492 fix(security): resolve reviewer findings on secret key baking, host symlinks, and injection safety
- Prevent baking SECRET_KEY into Docker image during collectstatic
- Persist runtime SECRET_KEY in data/secret_key volume or read from environment
- Remove sed-based injection of CSRF_TRUSTED_ORIGINS in favor of native os.getenv
- Avoid overwriting system python3 symlink on SUSE; auto-detect python 3.10+ binaries
- Make /etc/hosts entry in installer idempotent
- Add security notice regarding compute node VNC/SPICE port firewall isolation
