Add extra policy configuration for Guardian reviews (#47125)

Browse Source 
## What changed

- Add `auto_review.extra_policy` and the managed `guardian_extra_policy` requirement to supply policy text alongside the resolved tenant policy. Nonblank managed values take precedence; blank values are ignored.
- Render the additional text through `{{ extra_policy }}` in Guardian reviewer templates and append it to the tenant policy for Guardian v2 classification before truncation.
- Preserve placeholder-like text inside supplied policies literally.

## Testing

Add coverage for configuration precedence, blank values, template substitution, and classifier prompts, plus a scenario verifying that managed tenant and extra policies reach the Guardian reviewer together.
