feat: show spell failure reason in chat from SMSG_SPELL_FAILURE

Browse source 
SMSG_SPELL_FAILURE carries a failReason byte (same enum as SMSG_CAST_RESULT)
that was previously ignored. Now parse castCount+spellId+failReason and
display the localized reason string for the player's interrupted casts
(e.g. 'Interrupted', 'Stunned', 'Can\'t do that while moving').
