Issue Summary

A user with an expired tenant.session.token cookie (token expired) gets a misleading "We can't find the public link" error on a valid public Confluence link.

In network calls we can see:
POST /gateway/api/graphql/slow?q=SharedContentQuery:  does not apply the same anonymous fallback → returns 401

Steps to Reproduce

1. Log into Confluence and let the session token expire (after ~30 days, or simulate with an expired token)

1. Without loading any other Confluence page (which would refresh the token), open a public Confluence link

1. Observe the "We can't find the public link" error

Expected Results

Public links should load for all users. 

Actual Results

Public Confluence link shows fails to load and displays error "We can't find the public link"

Workaround

Open any normal logged-in Confluence page first (refreshes the token), then retry the public link. Or use Incognito.
