feat: add debuff dot indicators on hostile target nameplate

Browse source 
Show small colored squares below the health bar of the current
hostile target indicating player-applied auras. Colors map to
dispel types from Spell.dbc: blue=Magic, purple=Curse,
yellow=Disease, green=Poison, grey=other/physical.

Dots are positioned below the cast bar if one is active,
otherwise directly below the health bar. They are clipped
to the nameplate width and only rendered for the targeted
hostile unit to keep the display readable.
