fix(mail) : corrige le fetch IMAP réel contre OVH (listMessages cassé)

Quatre bugs révélés en testant contre une vraie boîte OVH (les tests mockaient
le provider, donc jamais exercés) :
- requête sans critère → "BAD parse error: zero-length content" : ajout de whereAll()
- getDate()/getSubject() renvoient des Attribute webklex v6, pas des scalaires : casts explicites
- séquence par défaut ST_MSGN → le peek() de webklex faisait un STORE par numéro de
  séquence rejeté par OVH ("flag could not be removed") : force ST_UID sur toutes les requêtes
- snippet via getTextBody() forçait un fetch de corps par mail (sync 179s + peek) :
  setFetchBody(false) au listing, snippet désormais optionnel

Sync INBOX : 9 messages en 1,6s (avant : échec en 179s).
