feat(sprint5): quest system + arcs + rebalance endurance/damage/xp

Quest system:
  4 entities (quest_arcs, quests, player_quests, player_quest_arcs)
  Arc "Les Marais du Têtard" (4 quêtes narratives)
  3 quêtes standalone répétables (chasse/forge/craft)
  5 achievements liés (quests_completed + quest_arc_completed)
  Event-driven: combat/forge/craft/loot émettent quest.progress
  API: available, active, completed, accept, claim, arcs

Rebalance:
  Endurance coût combat 10→5, regen 6min→3min (20/h), repos 20→10
  Dégâts joueur +3 base (plus de combats de 13 tours au level 1)
  Défaite endurance penalty 50→25
  XP monstres réduite (25→8 Têtard, 130→50 Golem) — quêtes = source principale
