fix(deploy): stop pinning API_ORIGIN, and probe one origin not the list

Two leftovers from making the browser derive the API origin. The stack env still
injected API_ORIGIN from a repo secret, which pinned the origin again on every
deploy and would have re-broken an https front door with mixed active content.
Drop it from both env_data blocks; the secret stays, now purely as the URL the
verify step probes.

That verify step was also about to break on its own: WEB_ORIGIN is a
comma-separated CORS list now, and `curl "$WEB_ORIGIN/version"` on a list
retries thirty times and fails a deploy whose app is perfectly healthy. Probe
the first entry, so keep the runner-reachable origin first in the secret.
