[IMP] project_key - add task key for portal users

[jdidderen]

I have added the task key in all the views related to the portal (read or edit)

For the edit part :

For the read part :

Currently the key is not properly shown in the kanban :

And with the improvement in the kanban view, I solve an issue when the kanban view is opened from the portal:

With the improvement, I replaced the URL with a highlighted key in the kanban view.
