[DX-4048] support dynamic host port mapping for ChIP Ingress and Router

[Tofel]

why? to solve CI port collisions like:

Error: failed to start environment: failed to setup test environment: failed to start chip router: start container: container start: Error response from daemon: failed to set up container networking: driver failed programming external connectivity on endpoint chip-router-0f2f3 (f1100fb23598a5f9d398ba758663cc4f25d53872e3c7ce1552bca37eedd18e6a): failed to bind host port for 0.0.0.0:50050:172.18.0.2:50050/tcp: address already in use

Pull request overview

This PR aims to eliminate CI port-collision failures by allowing Chip Ingress (docker-compose stack) and Chip Router (testcontainers container) to use dynamically allocated host ports, while also updating related examples and CI workflows.

Changes:

• Add dynamic host-port allocation for Chip Ingress gRPC and Chip Router gRPC/admin endpoints.
• Rename Chip Ingress image/port environment variables toward a CTF_ prefix and adjust wait/health behavior.
• Add/adjust smoke examples and GitHub Actions workflows to exercise the updated components.
