fix: nameplate click hitbox used name text width, not health bar width

The click region for targeting via nameplates was bounded by the name
text (nameX to nameX+textSize.x). Short names like "Wolf" produced a
~30px clickable strip, while the health bar below was 80px wide. Clicks
on the bar outside the name text bounds were ignored. Now uses the wider
of name text or health bar for the horizontal hit area.
