fix(HoverCard): drop duplicate update:open emit declaration

defineModel('open') already registers the update:open emit, so the
separate defineEmits<HoverCardEmits>() declared it twice and triggered
a Vue dev-mode duplicate-emit warning. Let defineModel own the emit and
remove the now-unused HoverCardEmits type and its re-export.
