Pass S3 endpoint and keys as helper container env vars and run mc alias
via those variables so the stored import command no longer contains
access keys or secrets. Start the helper in a separate remote process,
use the storage filesystem adapter for object checks, and remove a
credential temp file during import cleanup when the path is safe.
Move database import temp/container cleanup into a queued listener with retries, and clear the import running state on failed restore starts. Tighten Cloudflare replace/delete to the current server IP and owning resource, notify when DNS jobs fail, and pass domain-removal confirmation through remove-by-key. Document import request oneOf schemas without extra properties.
