Oliver Kieselbach 1554540431 web: one API call layer (fetchJson/fetchOk/fetchBlob), notifyError, ratchets with the full baseline (audit package 5, stage 1) ...

lib/scopedFetch.ts becomes lib/apiClient.ts: ApiError carries retryAfterSeconds (body first,
Retry-After header second), fetchJson<T> refuses empty and malformed 2xx bodies instead of
handing back undefined, sets Content-Type for string bodies, fetchOk covers action calls and
fetchBlob downloads. describeApiError renders 429/503 with the server's retry advice;
apiErrorText is the one-string form for inline error slots; apiErrorNotification folds the
"Session Expired" dialect into one place and NotificationContext.notifyError uses it.
useAuthenticatedFetch throws ApiError (correlation id preserved), drops the dead 204 branch
and onTokenExpired. dedupedFetchJson<T> for the three feature-flag readers.

lib/__tests__/apiClient.guard.test.ts ratchets raw authenticatedFetch(/dedupedAuthFetch(/
.json()/instanceof TokenExpiredError per file against a baseline that may only shrink
(a count above fails as a new site, below as a stale entry); fetchJson without a type
argument is a violation. Baseline today: 228 raw fetches, 221 parses, 140 token checks.
