Expose Browser Use requirements through the app server (#35033)

## What changed

- Parse the `browser_use.disable_auto_review` setting from layered
  `requirements.toml` configuration.
- Return the setting as `browserUse.disableAutoReview` from
  `configRequirements/read` and publish it in the generated JSON and TypeScript
  schemas.

## Testing

- Add an app-server RPC test covering the Browser Use requirement.
