Pull request overview

This PR enhances the ros2 action info command to align more closely with the verbosity and endpoint-detail capabilities of ros2 topic info -v / ros2 service info -v, by leveraging ActionEndpointInfo over the ros2cli daemon/XML-RPC boundary.

Changes:

• Extend ros2 action info to print the action type (Type: ...) in the default output and add -v/--verbose to print detailed endpoint info.
• Add XML-RPC marshalling support for rclpy.endpoint_info.ActionEndpointInfo and expose new daemon RPC methods for action endpoint info and action client/server counts.
• Add/extend CLI and daemon tests to validate the new action info output and RPC surfaces.
