Make history and notes tools Bridge-compatible (#40775)

## What changed

- Express nullable history and notes arguments with `anyOf` and remove unsupported schema constraints.
- Forward valid JSON object arguments to the backend without enforcing client-side limits.
- Clarify history ID, ordering, cross-agent path, and consistency semantics in the tool descriptions.

## Testing

- Cover forwarding previously restricted argument values for every history and notes tool.
- Verify app-server requests expose the Bridge-compatible schemas and still reject non-object arguments locally.
