ci/woodpecker/push/ci Infra-only: compose YAML fix, no app code
Service definitions were using 'openbrain_brain-internal' (underscore) but the
networks block defines the alias as 'openbrain-brain-internal' (hyphen), with
name: openbrain_brain-internal pointing to the actual Docker network.
This caused 'undefined network' errors on every Portainer deploy for
orchestrator and synapse services.
Fixed: all service network references now use 'openbrain-brain-internal'.
