Record Guardian context mode in review and classification telemetry (#49294)

## Why

Guardian review and classification telemetry lacks the context mode needed to distinguish `legacy`, `independent`, and `thread_owned` reviews.

## What changed

- Add `guardian_context_mode` to review and classification analytics and `context_mode` to their metrics.
- Capture the mode from the conversation history snapshot before review preparation or classification setup so failure metrics retain it, including when review preparation or reviewer startup fails.
- Use `unknown` for review metric tags when no context mode is available.

## Testing

Update metric assertions to cover `thread_owned` classification tags and the `unknown` review fallback.
