Fix character screen weapon slots layout positioning

Position weapon slots (main hand, off hand, ranged) to align with the right
column instead of appearing in the left column where they crowd the main
equipment slots (tabbard, bracers, etc.). Weapons now positioned consistently
with the 3-column layout at rightColX instead of appearing at the default left
cursor position.
