Use trusted Guardian templates for managed policies (#60646)

Browse Source 
## Why

User-configured model catalogs can supply Guardian prompt templates that omit policy slots or add conflicting instructions. Managed rules need a trusted template to reach the reviewer.

## What changed

- Use the bundled Guardian policy template when managed policy or additional rules are present, while preserving explicit host-provided templates.
- Remove `auto_review.extra_policy` and `auto_review.experimental_policy_template` from configuration and the schema. Warn when they are used, directing additional rules to `guardian_extra_policy` in managed `requirements.toml`.

## Testing

Add regression coverage for managed rules with user-supplied catalog templates, explicit host templates, and migration warnings for the removed settings.
