feat(badge-leaderboard): render avatar heads with the local renderer

The leaderboard rows pulled each avatar head from habbo.com's imaging
service (`https://www.habbo.com/habbo-imaging/avatarimage?...headonly=1`)
via a plain <img>. The avatar `figure` is already present in the leaderboard
data (served by the CMS `/api/badges/leaderboard` endpoint), so there is no
need for an external request - render it locally instead.

Swap the <img> for the renderer-backed `LayoutAvatarImageView` (headOnly),
which draws the head through `GetAvatarRenderManager().createAvatarImage(...)`.
The head-only render is an absolutely-positioned background div rather than an
<img>, so the avatar CSS is reworked to frame it (relative, overflow-hidden
box with a head crop mirrored from the friends list), and the now-unused
`getAvatarHeadUrl` helper is removed.

Removes the last runtime dependency on habbo.com for this panel; avatars now
come entirely from the local renderer.
