Migrate to latest offline-phragmen

[mariopino]

The latest offline-phragmen by kiaenigma already have json output so there is no need to keep using the modified version.

The output is different so we should do a data transform at backend level or modify the whole implementation. My vote goes to transform the data at backend level so we don't need to change the frontend.
