 * push its body — a phone photo on a slow uplink, a 500 MB document — is aborted
 * mid-stream, which the server reports as a multer "Request aborted" (#1495).
 *
 * Every upload therefore has to opt out with `timeout: 0`. That opt-out used to be
 * hand-written per call site, so it was forgotten on 7 of 15 — including the two 500 MB
 * endpoints (documents, backup restore). Centralizing makes the correct behavior the
 * default instead of something you have to remember.
 *
 * The Content-Type is set for clarity only: axios unsets it for FormData in the browser
