translations: use server side translations

* Adds new assets directory for the admin project.
* Moves translations files to the assets directories.
* Removes custom translations loader.
* Fixes bad translation string definition.
* Adds assets and backend translations URLs configurations.
* Removes useless manual translations.
* Fixes missing languages for translation extractions: ar, nl, es.
