List every domain configured across the account's applications

Returns a flat list of every hostname configured across the applications owned by the caller: the default <subdomain>.squareweb.app hostname (type: "subdomain") and any attached custom domain (type: "custom"). Custom domains are listed first, followed by the default subdomains. Applications without a web domain are omitted.

Served from the cached project list, so it does not count against the per-application network rate limits. Rate limited to 20 requests per 60s per user.
