Fix failing tests: route path, auth dependencies, cost_breakdown, and TTL test

- Fix test_mcp_connection_requires_auth_dependency: Use correct route path /mcp-rest/test/connection
- Fix test_update_ui_settings tests: Use app.dependency_overrides instead of monkeypatch for FastAPI dependencies
- Fix test_spend_logs_payload tests: Add metadata.cost_breakdown to ignored_keys (optional field)
- Improve test_async_increment_tokens_with_ttl_preservation: Increase wait time and add debug logging
