startPreInstall called installLibrePortalImageWebUI standalone AND then
installLibrePortalAppWebUI, whose app-install step 1 builds the same image
again — so a fresh install built libreportal-service twice back-to-back
(2nd mostly Docker-cache hits, but a redundant copyFolder + "this may take a
while" block). The standalone call only matters on a rebuild where the
app-install path SKIPS (libreportal already in the DB). Gate it on exactly
that: build standalone only when libreportal is already installed. Net: one
build in both cases (fresh → via app install; reinstall → standalone).
