fix(lint): fix remaining PLR0913 (too-many-args) violations

- Extract highest_risk_percentage from response_payload in
  _log_guardrail_result instead of passing as a param
- Introduce DataSourceConfig dataclass to bundle name/enabled/priority
  for URLDataSource, VectorStoreDataSource, FactCheckDataSource
