Dockerfile: fix MCP config path, skills repo name, cache-bust arg

- Point both claude-code and codex at the real altinity-mcp config
  mount /etc/altinity-mcp/config.yaml (was stale /opt/expert-mcp/*,
  and the two agents disagreed); matches the skills-agent Helm secret.
- Fix skills source path Altinity/Skills -> Altinity/altinity-skills
  (repo was renamed).
- Reference TOOLCHAIN_REFRESH in the install RUN so changing it
  actually busts the toolchain layer cache (CI passes github.run_id).
- Drop redundant chmod 755 on /etc/claude-code.
