fix(conditions): rename trade condition 61 to PRICEVOLUMEADJ (#480)

The display name carried a third-party product mark inherited from the
upstream condition dictionary. The description ("Used to make volume
and price corrections to match official exchange values") already
describes the purpose, so the renamed `PRICEVOLUMEADJ` constant
captures intent without the vendor reference. Single tracked
occurrence, no downstream string match.
