Use captured action settings for Guardian reviews (#44574)

## Why

Model changes during a turn and catalog refreshes can leave Guardian reviews using settings or metadata that do not match the action being reviewed.

## What changed

- Use the action's captured model, reasoning effort, reasoning summary, and personality when configuring reviews.
- Preserve captured model metadata when falling back to the parent model, while resolving a separate reviewer against the current catalog on each attempt.
- Evaluate live managed review requirements against the action's model and use its metadata for computer-use review behavior.
- Include personality in the review session reuse key so personality changes invalidate cached sessions.

## Testing

Add regression coverage for delayed and new actions across model changes and catalog refreshes, required-review routing, and session reuse when policy or personality changes. Extend integration tests to cover reviewer reuse across parent model changes and verify that interrupted reviews cannot execute commands after a delayed approval arrives.
