chore(roles): role/test hygiene from review (O16,O17,O25,O26)

- dev_env .zshrc: drop the rclone alias (not installed) and guard the direnv
  hook with `command -v direnv` so a missing direnv doesn't error every shell (O16)
- dev_env oh-my-posh: tag the zen.toml theme deploy `config` (it renders config to
  disk like the per_user dotfiles); the include now carries packages+config so a
  `--tags config` run re-renders the theme while the binary install stays packages
  only (O17). Verified via `molecule converge -- --tags config`.
- drop the non-vocabulary `tags: [verify]` from molecule verify playbooks across
  base/docker_host/public_dns/reverse_proxy (check-tags exempts molecule anyway) (O25)
- reverse_proxy templates: add the `{{ ansible_managed }}` header (ADR-024 §1.2) (O26)

make lint green; dev_env + reverse_proxy molecule green.
