Live dark previews of this deployment, one per branch

Every live preview: the branch, its .onion, and when it expires. git_credential_source is the parent deployment ID when a private preview uses its parent Git connection; otherwise null. Credentials are never returned.

A preview is a normal deployment with the clearnet half removed — a fresh Tor v3 hidden service minted on your own box, no DNS record, no certificate, no Certificate Transparency entry. That is the difference from every other platform's preview URLs: theirs put each branch name into public DNS and into an append-only, worldwide-mirrored CT log, and branch names carry ticket ids, customer names and unshipped feature names.

url is the onion or null. It is never a clearnet address; a preview that somehow has one comes back with a warning and should be reported, because it means the branch name went public.
