feat(progression): quêtes rotatives court-terme + panel HUD

Nouvel autoload QuestManager avec 11 templates (casser X sable, récolter
coraux, collecter perles, plonger à -25m, crafter 2 objets, etc.).
3 quêtes actives simultanément; complétion → récompense XP + roll d'une
nouvelle quête.

HUD: panneau "OBJECTIFS" top-right avec progression couleur (gris→vert),
bannière centrale "✓ QUÊTE" + son bulle au complete.

Motivation moyen-terme (5-15 min): le joueur a toujours qqch à faire.
