Syntax error and Validation error

[abhibongale]

1. Sushy-tools config syntax error (stackbox/templates/sushy/sushy-emulator.conf.j2:5,9,12)

• Added quotes around string values ("libvirt", "qemu+tcp://...", "0.0.0.0")
• Flask's from_pyfile() uses exec() so values need to be valid Python syntax

2. Tempest path validation error (stackbox/cli/main.py:541,546,568,594)

• Changed .relative_to(Path.cwd()) to .relative_to(config_dir_path)
• Path.cwd() was wrong reference when working directory differs from project directory

3. Sushy-tools healthcheck failure (stackbox/templates/docker-compose.yml.j2:82)

• Changed from curl (not installed) to python3 -c "import urllib.request; urllib.request.urlopen(...)"
• Container is now healthy

4. Tempest build using wrong command (stackbox/cli/main.py:574)

• Changed hardcoded docker-compose to runtime-detected command
• Now uses get_compose_command() to support both Podman and Docker
