Dokploy: Command Injection via incomplete shell escaping in docker logout (registry deletion)

Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.29.0 and earlier, the deleteRegistry function in Dokploy (packages/server/src/services/registry.ts) executes docker logout ${response.registryUrl} without shell escaping. In the same file, the docker login command correctly uses shEscape() to prevent command injection. This inconsistency creates a command injection vulnerability when deleting a registry with a crafted registryUrl.
