ARR: Add new links in SAC/AC console

[haroldrubio]

This PR separates ARR SAC and AC consoles and loads in new invitations:

const perPaperInvitations = (perPaperInvitationSuffixes && notes.length > 0) ? await api.getAll(
  '/invitations',
  {
    ids: perPaperInvitationSuffixes.map((suffix) =>
      notes.map((note) => `${venueId}/${submissionName}${note.number}/-/${suffix}`)
    ).flat(),
  },
  { accessToken }
)
: []

by reading the Webfield config variable perPaperInvitationSuffixes in order to support links to other forum pages linked to that submission ("Edit Commentary Readers"):

The intended use case is to give the PCs/SACs/ACs a new forum where they can control a part of the workflow for that submission only. Using the existing submission forum for this may be too cluttered.
