fix(hud): populate KeyBindRow display fields so module names render

The render path in KeyBindsHud.renderRows draws row.displayName /
row.keyName and lays out rows using row.nameWidth, but the
KeyBindRow constructor (and update()) only assigned name/key,
leaving displayName, keyName and nameWidth at their default null/0.
That's why only the 'Hotkeys' header showed up while every module
row stayed blank with zero width.

Initialize displayName, keyName, nameWidth and widthValue from name
/ key in both the constructor and update().
