Create artisan command for manual package provisioning, replacing the
need to use Tinker. The command accepts workspace ID/slug and package
code, validates inputs, shows a summary, and confirms before
provisioning. Supports --dry-run, --force, --expires-at,
--billing-anchor, --blesta-service-id, and --source options.
