Match the short-functional naming convention used by the other vhosts
(git, auth, dash, flow, ml, hub, ops, mq, ci, mqtt). FROST implements
OGC SensorThings API, so `sta` is the natural fit.
portainer.wbd-rd.nl is dropped from deploy.sh HOSTS — there is no
nginx vhost for it; portainer is already served via ops.wbd-rd.nl.
DNS prereq for first deploy is now: create one new A record for
sta.wbd-rd.nl → cloud public IP. All other short subdomains already
point correctly.
