Do not show locked banner if backend sends restrictions.allowUpdate=false

[MichaelBuessemeyer]

Context

When an annotation with othersMayEdit turned on is shared publically and another user from a different organization opens the annotation a locked banner is shown. This might be confusing as the annotation is not locked but the user is not allowed to edit this annotation due to being from another organization (see #7923).

Expected Behavior

No logged banner should be rendered.

Current Behavior

A logged banner is rendered. See https://github.com/scalableminds/webknossos/pull/7923#issuecomment-2233712513.
