Pull request overview

Fixes ranger-pdp startup/installation in the Docker-based environment by ensuring required runtime libraries are available in the PDP build and assembled distribution, and by aligning the PDP compose network definition with the main Ranger compose setup.

Changes:

• Add missing JAXB and Activation API dependencies to the ranger-pdp Maven module.
• Ensure the PDP distro assembly explicitly includes the JAXB/Activation API JARs.
• Adjust Docker Compose network configuration for the PDP compose file to avoid requiring an external pre-created network.
