Why

The changes streamline the use of endpoints within the Canton testing framework and update the Canton and Splice images to newer versions. This includes a structural change to how network-specific data for Canton is organized and accessed, improving clarity and maintainability of the codebase. Additionally, the update supports Docker-internal networking, enhancing the setup's flexibility and alignment with containerized environments.

Pull request overview

This PR adds Docker-internal networking support to the Canton Nginx container by changing Nginx server_name directives to wildcard patterns and explicitly registering all internal hostnames as Docker network aliases. It also restructures the Canton output to expose both internal (Docker-network-only) and external (Docker-host-reachable) endpoints, and bumps the Splice/Canton image versions from 0.5.11 to 0.5.13.

Changes:

• Split CantonEndpoints output into a new CantonData type containing separate InternalEndpoints and ExternalEndpoints fields
• Changed Nginx server_name directives from *.localhost to wildcards (*.*) and added all internal hostnames as Docker network aliases
• Bumped Canton/Splice images to v0.5.13 and updated smoke tests and documentation accordingly
