Fixes#1245. Deduplicate the anonymous-chat file upload request, which
was inlined verbatim in DocumentsSidebar.tsx and free-composer.tsx
while anonymousChatApiService.uploadDocument already existed.
Key change: service now returns a discriminated result instead of
throwing on 409. Callers need to distinguish 409 (quota exceeded, ->
gate to login) from other non-OK responses (real errors, -> throw).
export type AnonUploadResult =
| { ok: true; data: { filename: string; size_bytes: number } }
| { ok: false; reason: "quota_exceeded" };
Both call sites now do:
const result = await anonymousChatApiService.uploadDocument(file);
if (!result.ok) {
if (result.reason === "quota_exceeded") gate("upload more documents");
return;
}
const data = result.data;
Dropped the BACKEND_URL import in both files (no longer used). Verified
zero remaining /api/v1/public/anon-chat/upload references in
surfsense_web/.
