Subject: Refactor: reduce duplication and tighten helpers

- Remove redundant applicationUri log in print_application_description
- Use UA_SECURITY_POLICY_NONE_URI macro instead of hardcoded string
- Extract _s_register_with_lds / _s_deregister_from_lds helpers
- Rename signal handler param 'sign' to 'sig' for consistency
- Add INT_MIN/INT_MAX bounds check to config_require_int
- Extract shared test helpers into tests/test_helpers.sh
