5402: Update dev compose for split FPM_SERVICE/FPM_PORT

After PR #409 unified the dev and prod nginx templates, the dev
compose stack also consumes the production template — but it still
passed NGINX_FPM_SERVICE as a combined 'host:port' string. With the
template change in this PR ('server ${NGINX_FPM_SERVICE}:${NGINX_FPM_PORT};'),
that produced a malformed 'display-phpfpm-1:9000:9000' upstream and
nginx failed to start, breaking the Playwright CI run.

Split the value in both docker-compose.yml and docker-compose.server.yml.
