fix(tests): correct provider.service and chat-security test assertions

- Fix ProviderService constructor call: pass null for optional credentialsService
- Update Anthropic model order to match AnthropicAdapter registration (opus first)
- Update OpenAI model list to match OpenAIAdapter (codex-gpt-5-4 only)
- Update Z.ai assertion to verify glm-5 is present (Pi registry includes additional models)
- Add reflect-metadata import to chat-security test to fix Reflect.getMetadata error
