Internal Server Error after returning from Authelia: processOAuthCallback threw
OAUTH_INVALID_RESPONSE ("unexpected state parameter") because the OIDC state
cookie no longer matched the state returned to /callback.
Root cause: eventsQuery (fetchEvents, redirect:'follow', retry:2) ran
concurrently with fetchMe on load. While unauthenticated, every /api/* request
hits the OIDC guard, which 302-redirects to Authelia AND sets a fresh state
cookie. fetchEvents could not follow the cross-origin redirect, so React Query
retried it up to 3x over ~3s — each retry overwriting the state cookie mid-login,
racing the single /api/login navigation that owns the real flow.
Fix: enabled: meQuery.isSuccess. Only fetchMe (redirect:'manual', retry:false)
touches a guarded endpoint while unauthenticated, so the top-level /api/login
navigation owns the state cookie uncontested. Realizes the documented design
intent that only fetchMe drives the login redirect.
