scanopy: make the rollback restore the whole old setup

Browse Source 
The health check put the previous binary back but nothing else, and the
source tree it needs was already gone by then: the update deleted
/opt/scanopy/ui before starting the new server, and removed
SCANOPY_WEB_EXTERNAL_PATH from the env at the same time. A failed
health check therefore left the old binary running without the UI it
serves from disk, so the rollback produced an API-only server.

Back up the env file and the unit alongside the binary, restore all
three when the check fails, and delete the source tree only once the
new server has answered. Nothing the old version needs is removed
before the new one has proven itself.
