fix: move buff bar to top-right, split buffs/debuffs, raise aura cap to 40

- Relocates buff bar from top-left Y=145 (overlapping party frames) to
  top-right (screenW - barW - 10, 140) where it doesn't conflict with
  party/raid frames anchored on the left side
- Increases max shown auras from 16 to 40 (WotLK supports 48 slots)
- Two-pass rendering: buffs shown first, debuffs below with a spacing gap
  between them; both still use green/red borders for visual distinction
- Widens row to 12 icons for better horizontal use of screen space
