[Bug] Connecting with 3DS with no PNID linked gives 015-5015

[DaniElectra]

When trying to open Juxtaposition on the 3DS with no PNID linked, the error 015-5015 is displayed. This is because if the Miiverse applet detects there is no PNID linked, it will try to contact discovery with no X-Nintendo-ServiceToken header set, which ends up with discovery returning the NO_TOKEN error:

miiverse-api/src/middleware/auth.ts

Line 43 in 2af8d74

return badAuth(response, 15, 'NO_TOKEN');

I feel like this isn't intended behavior, and a landing page telling the user to link a PNID should be given instead, just like rverse does:

If I remember correctly, Miiverse had a "guest mode" which would let you view posts but not create any? This is likely what should happen instead imo
