UI fixes in user profile (structure)

Some changes are needed in the new structure selection process (user profile)

when selecting a structure after clicking on the button below structure selection box :

• french translation is incorrect in return link (profile instead of profil).
• for me, it was not easy to understand that you need to click on a check mark at the end of the line, maybe a standard button with text ('choose' or 'validate') would be more appropriate.
• after validating structure choice, we should send the user back to profile page.
• translations are missing in french ('choose your attachment structure' and 'no options' in structure select list)

in profile page, I think the current user structure does not appear clearly (maybe it should be in bold text or something like that)
