nampower: Use SetSize, UnitClassBase and simplify icon logic

Replace SetWidth/SetHeight with SetSize for pfUI.spellqueue and reactive icons. Use UnitClassBase("player") to obtain the player's class token. Simplify reactive icon visibility by using SetShown and aggregating a single anyVisible flag, then calling SetShown on the parent frame. Minor readability and API modernization changes.
