fix: resolve hud actor from hud.token not render context param

V2 renderTokenHUD passes (hud, html, data) where data is a render
context object — not a TokenDocument.  data.actor was undefined,
and data?.token?.actor was also undefined.  Use hud.token.actor
(or hud.object.actor) instead, which is the real PlaceableObject
with proper actor resolution.

Also fix html.find() → html.querySelector() for V2 HTMLElement.
