fix(views): drop disableHoverCard from QuickCreate modal ActorAvatars

The ActorAvatar prop was renamed in #1794 (split presence into
availability + last-task) — `disableHoverCard` is now `enableHoverCard`
with inverted semantics. The QuickCreate modal landed against the old
API and broke main's frontend typecheck. The two avatars in the modal
already want the default (no hover card), so just drop the prop
instead of opting in.
