Fix(spells): saut reel pour Bond heroique & sorts JUMP_DEST

Browse Source 
CalculateJumpSpeeds lisait MiscValue/MiscValueB de SpellEffect comme une
vitesse verticale brute (speedZ = MiscValue/10), alors que la data DB2 7.3.5
moderne y stocke les hauteurs d arc min/max (en 1/10 yard). Pour le saut de
Bond heroique (94954: MiscValue=25, MiscValueB=100) cela donnait speedZ=2.5
-> arc plat ~0.16y + vitesse horizontale enorme = glissade facon Charge au
lieu d un vrai saut.

Portage du calcul base hauteur: speedXY derive de la vitesse de course,
hauteur d arc bornee entre MiscValue/10 et MiscValueB/10, convertie en
speedZ = sqrt(2 * gravity * height). Corrige tous les SPELL_EFFECT_JUMP_DEST
(Bond heroique, Desengagement, sauts Chasseur de demons, ...).
