feat(tickets): affiche le créateur d'un ticket et filtre la liste par créateur

createdBy était déjà présent dans le frontmatter des tickets mais ni exposé
ni exploitable côté UI. Ajout du DTO (domain/ports/mock), affichage dans
TicketDetail, colonne/filtre créateur dans TicketsPanel, et persistance du
filtre. ticketActor.ts introduit pour porter la logique de filtrage côté
frontend, sans changement backend nécessaire (lot frontend pur).
