fix: quest available filtering + 6 side quests level 2-4

Fix: getAvailable filtre maintenant les quêtes active/completed (pas juste
claimed). Plus de doublons dailies, plus d'internal server error.

6 quêtes secondaires pour combler le gap level 2-5:
  Chasseur de champignons (lv2, 150 XP), La menace rampante (lv3, 180 XP),
  Guerrier éprouvé (lv2, 250 XP), Collecteur de trophées (lv3, 500 XP),
  Exterminateur (lv4, 400 XP), Première forge (lv2, 120 XP).
