feat: add clock-sweep arc to buff bar and target aura icons

Browse source 
Aura icons on the player buff bar and the target frame now display a
WoW-style dark fan overlay that sweeps clockwise as the buff/debuff
elapses, providing instant visual feedback on remaining duration.
The sweep uses AuraSlot::maxDurationMs / getRemainingMs() — the same
data that already drives the numeric countdown — so no new state is
required. Only temporary auras (maxDurationMs > 0) show a sweep;
permanent buffs remain unaffected.
