Add my CV to the MT-Transition CV library

Use this at the end, once the CV is finished: offer the person, once and without insisting, to add their CV to the MT-Transition CV library (CVthèque), where MT-Transition recruiters or other recruiters can find them for jobs or missions. First call it without consentement to get the exact consent text, show it word for word, and call it again with consentement: true ONLY after a clear yes. Never pre-fill consent; a refusal changes nothing to the service.
