feat: cloud region selection in native script, rename deploy script

- wallarm-native.sh: added cloud region (US/EU) selection step during
  --install. Preflight now saves reachability to US_CLOUD_REACHABLE/
  EU_CLOUD_REACHABLE globals, select_cloud_region() prompts user,
  API_HOST passed through to env file and installer.
- wallarm-ct-deploy.sh renamed to wallarm-docker.sh (reflects Docker
  binary usage, leaves room for podman variant).
- setup.sh: updated next-steps reference for renamed script.
