In `@ecoscan_app/hooks/useAnalyzeProduct.ts`:
- Around line 88-90: Update the error handling in useAnalyzeProduct to preserve
the upstream HTTP response status on a typed error from apiClient, then classify
product-not-found responses by checking status 404 rather than matching
String(err). Keep unrelated messages from being treated as not-found, and add
tests covering a genuine 404 whose message omits the status and a non-404
message containing “404”.
- Around line 91-95: Update the catch handling in useAnalyzeProduct so
cancelAnalysis and handleStreamError cancellation/abort failures are rethrown
unchanged, preserving their user-facing behavior. Only convert unexpected
failures to the generic “Analyse fehlgeschlagen…” error, using the established
typed error codes or error types rather than matching message text.
