UnitAura "HARMFUL|RAID" only honours vanilla class dispel knowledge in
the 3.3.5 client — CoA custom classes (Chronomancer, Monk/Templar,
Prophet/Venomancer, etc.) were silently filtered to zero debuffs.
Fix: in updateGroup(), detect CoA dispellers via C_Player:IsCustomClass()
and store their per-class dispel set on group.coaRaidFilter instead of
appending |RAID. scan() skips debuffs whose auraType is not in that
set, preserving contiguous button layout with no gaps.
