felixxia-oai 4b1cf9a4c9 Use conversations for all Guardian v2 async classification (#56556) ...

## What changed

- Always use the retained conversation backend for asynchronous classification; keep snapshot sampling test-only.
- Accept legacy `async_classifier_mode` values in configuration and model metadata but ignore them. Emit a startup warning when `[features.guardianv2].async_classifier_mode` is configured.
- Ignore legacy classifier mode differences when checking model-switch compatibility, and fail closed if the conversation backend is missing.

## Testing

Update coverage for legacy configuration warnings, model-switch compatibility, retained approval-review context, and conversation-based scoring.
