reindexWorkspace isolated every per-page failure, so an invalid/missing
API key (401 "User not found") made all pages fail identically while the
batch kept issuing hundreds of doomed requests against the provider.
Add isFatalProviderError() (401/403 auth, 402 billing) and abort the
whole batch on such errors; 429 rate-limit and embedding timeouts stay
per-page isolated. Adds unit tests for the predicate and a regression
test for the abort/iterate control flow.

Provider auth failures were logged with the provider's opaque message only
(e.g. OpenRouter returns "401: User not found." for a bad/missing API key),
which reads like a missing wiki user rather than a credentials problem.
describeProviderError now prepends a clear, human-readable English label for
a small set of well-known HTTP statuses while keeping the original detail
(status + provider message + truncated response-body snippet):
- 401/403 -> authentication failed (invalid or missing API key)
- 402 -> insufficient credits or quota
- 429 -> rate limit exceeded
Other statuses and status-less errors are formatted exactly as before. The
label is a static string and never contains the API key. Benefits every
caller (embedding processor, indexer, AI "Test endpoint" UI) at once.
Tests: switch the plain status+message case to a non-classified status (500);
add 401/403/402/429 cases; keep 502/503 as regression guards for the
unchanged path.
Behaviour change (split out of the test commit per review, and now covered).
Both the stream onError log line and the error text streamed to the client were
formatted by separate inline blocks that only emitted "<status>: <message>".
Route both through the shared describeProviderError() so formatting stays in one
place.
BEHAVIOUR CHANGE: describeProviderError additionally appends a single-line,
300-char-truncated snippet of the provider responseBody/text. So the log line
AND the user-facing stream error now include that snippet (e.g. the HTML error
page from a misconfigured endpoint), which previously neither did. This is
intentional — it makes a misconfigured external endpoint diagnosable — and is
safe: the API key travels in the Authorization header and is never echoed in
the response body (see the util's docstring). A `fallback` param is added so
each call site keeps its own default ('AI stream error' for the stream).
Adds ai-error.util.spec.ts covering the formatter, including the appended /
truncated body snippet, so this behaviour is no longer untested.

A misconfigured embeddings endpoint failed the RAG indexer with an opaque
"Invalid JSON response" and was not caught by "Test connection" (which only
probed the chat model), so it only surfaced silently during background
indexing.
- add describeProviderError(): formats AI SDK errors as
"<statusCode>: <message> | response body: <truncated one-line snippet>"
(statusCode/message/responseBody never carry the API key)
- use it in the bulk-reindex catch and the embedding processor's formatter so
the real cause (e.g. an HTML 404 from a wrong base URL) is visible in logs
- testConnection now probes chat AND embeddings independently: skips a probe
when that capability is unconfigured, returns ok:false with a Chat:/Embeddings:
prefix on real failure, "not configured" when neither is set
