Since 355e89ce5, the frontend references resources via root-relative URLs. This means that `resources` dirs in the language dirs are no longer accessed and can be removed. Achieve this by defining a specific `assets` production config that doesn't include `src/resources`. As of fd35c8f4a, this shrinks the frontend size by 55% (279M -> 124M). Also, the nginx location configs now can be simplified.
