Add podman support and registry login to container scripts

[mcosgriff]

Summary

• Replace hard-coded docker / docker compose references with cached runtime detection that supports both Docker and Podman (including podman compose and podman-compose variants)
• Add registry_login before run, run-ubi, and build commands to avoid 403 errors when pulling images — logs into OPENC3_REGISTRY (core) and OPENC3_ENTERPRISE_REGISTRY (enterprise) using interactive credentials
• Apply matching logic to both openc3.sh and openc3.bat

Changes

openc3.sh

• detect_container_runtime() — cached function that finds docker or podman
• detect_compose_cmd() — cached function that finds the compose command ( compose or -compose), exports DOCKER_COMPOSE_COMMAND for backward compatibility
• registry_login() — sources .env, calls login on configured registries (prompts for credentials if not already authenticated)
• All docker and ${DOCKER_COMPOSE_COMMAND} references replaced with ${CONTAINER_CMD} and ${CONTAINER_COMPOSE_CMD}

openc3.bat

• Equivalent runtime and compose detection using where command
• :registry_login subroutine with matching logic
• All docker compose references replaced with !CONTAINER_COMPOSE_CMD!

scripts/linux/openc3_test.sh

• Uses exported DOCKER_COMPOSE_COMMAND from parent if available, otherwise detects runtime with podman support

scripts/linux/openc3_util.sh

• Fixed $@ → "$@" quoting in podman wrapper for proper argument handling

openc3/lib/openc3/utilities/store_queued.rb

• Wrapped the process_queue() call in shutdown with a rescue block. This fixes the CI failure where all tests pass but the at_exit hook raises Redis::CannotConnectError when Redis is unavailable during process shutdown, causing exit code 1.

Closes #3497

I made equivalent change to store_queued.py. This change forced me to login to docker.io during the build but I think that's ok. I previously was building fine without this login.

These changes can cause using podman-compose which is not supported. :(
