feat(progression): succès/achievements + toasts notification

Nouvel autoload AchievementManager avec 12 succès (Premier éclat, Mineur
confirmé, Chasseur de perles, Fouilleur d'épaves, Abysses, Légende des
océans, etc.). Chaque déblocage donne un bonus XP et joue un son.

HUD: toasts dorés avec icône + titre + desc + fade-in/out, empilés en
haut centre. Son bulle au déblocage.

Long-terme: cible des milestones cumulatifs qui donnent un sentiment de
progression durable.
