v0.11.5

Added

• Error.vue, the refusal and not-found screen. escalated-rails renders
  Escalated/Error for every 403 and 404 inside the panel and no component had
  ever existed behind it, so a refusal arrived as a blank page — and a refusal
  that says nothing is indistinguishable from a bug.

  It takes the status and the backend's already-translated message, and
  falls back to its own wording when a status arrives bare. Like the two-factor
  challenge it does not use EscalatedLayout: the usual reason to be here is
  having been refused, and the layout's navigation is a list of places the
  viewer may equally not be allowed to go. The way back is rendered only when
  the backend says where that is.

pages.json is now 91 pages. Backends check their rendered page names against
it; see CONVENTIONS.md in escalated-developer-context.
