When adding a domain via the API, the domain must already resolve to the Ploi Cloud IP before it can be added. This blocks automated provisioning workflows where DNS records are created in the same script that registers the domain on Ploi. Requested changes:

1.	Accept unverified domains — Allow adding a domain even if DNS hasn’t propagated yet. Mark it as “pending verification” and issue the SSL certificate once DNS resolves.

2.	Automatic background verification — Periodically re-check pending domains (e.g. every 60s for 24h) and activate them once DNS resolves, instead of requiring the user to re-submit.

3.	Automatic cleanup of invalid domains — Domains that never pass verification within a configurable window (e.g. 48h) should be automatically removed, preventing stale entries from accumulating.

This would enable fully automated domain provisioning pipelines where Cloudflare zone creation, DNS record setup, and Ploi domain registration happen in a single command without needing to wait for propagation between steps.
