The overview background graph and the Knowledge Base graph both rendered
empty because the SPA's OIDC access token expired (~5 min TTL) and was
never refreshed. fetchWithAuth called getToken() synchronously (no refresh);
ensureToken returned the stale token without refreshing; storeTokens
discarded expires_in; the resulting 401 made fetchGraph return null and
both graphs drew nothing, with no error surfaced.
- oidc.ts: track expiresAt from expires_in; getToken() returns null within
30s of expiry; ensureToken/initOIDC refresh instead of returning stale
tokens; isOIDCConfigured no longer claims configured on expired-only state
- config.ts: fetchWithAuth awaits ensureToken (refresh on demand), falls
back to static token if OIDC can't yield one, flushes OIDC session on 401;
sseUrl is async + refreshes before constructing the EventSource
- stores/events.ts: connect() awaits the now-async sseUrl
