Finalize test orchestration refactoring and improve error messaging

- Refactor run-tests-isolated.bash to provide explicit error messages for missing infras.
- Reference infras.lst in error output to clarify setup requirements.
- Standardize README.md with updated orchestration roles and manual guide.
- Ensure all literal placeholders are preserved in docker-compose.yml files.
