Upload a report image
Upload a public HTTPS image or canonical base64 PNG, JPEG or WebP (maximum 1MB) to the selected workspace. Requires reports:write, current author permission and report-authoring availability. The UUID Idempotency-Key identifies one immutable upload. Preserve the identical request on retries: completed uploads reuse stored bytes; a conflicting command or changed reserved content returns 409. The result is an active native image asset usable through settings.assetId; it is distinct from a workspace logoId. Does not change workspace branding, report content, Data, sharing or PDF state.
