[home] Introduce Claude Code settings.json installed via Guix home.

- Add claude/.config/claude/settings.json with model overrides, max
- effort and apiKeyHelper wired to pass.
- Add conf/home/claude.scm service module bundling the claude-code
  package with its dotfile.
- Wire claude-service into home.scm, replacing the raw claude-code
  package.
