feat(dispatch): tech-history resolue via identite canonique (dynamique)

Le rapport techHistory groupe desormais par IDENTITE (lib/identity resolveIdentity:
staff_id -> nom), calculee A LA LECTURE -> corriger une identite (onglet Settings
Identites) reclasse le ledger AUSSITOT (pas de valeur figee).
- is_tech = l identite a un tech_id : le staff admin (ex. Megane Liaud, sans tech_id)
  n est PLUS compte comme technicien.
- Sortie: par assignee {label,email,is_tech,kind,total,from_pool} + liste unresolved
  (noms sans identite, ex. prenom seul) a mapper dynamiquement.
- Detail ?tech= accepte cle identite | courriel | tech_id | staff_id | nom.
