Various fixes: profilePicture / logo upload, imageIdentifiers (#6530)

In this PR:
- refactoring auth module to extract a jwt module that can be re-used
from other part of the app (avoiding circular dependencies file module
=> auth => file (file and auth both need jwt actually)
- activating imageIdentfier on person on workspace creation (this will
put back the images on people)
- fixing picture upload (we were missing some fileToken)
