act_runner mangles boolean input defaults: format('{0}', inputs.warnaserror)
evaluated to '%!t(string=false)', so -warnaserror was never passed.
Input is now a string defaulting to "true"; anything but "false" enables it.
Build command is traced (set -x) so the log shows the flags used.

Separate file because Gitea can't make services: conditional.
Service is reached by name on the job network; POSTGRES_* env is
passed to the test step.
