/**
 * Sends the diagnostics zip to Desktop Commander's diagnostics Worker, which
 * stores it for 7 days and answers with a report id the user gives support.
 *
 * The address comes only from the server's /api/mcp-info `diagnosticsUrl`, so
 * the Worker can move without a release. When the server names none, nothing
 * is uploaded and the zip stays saved.
 * The ids only sort the upload into a folder: the user id is the saved access
 * token's `sub`, read locally like blocking-offline-update.js reads `exp`, and
 * the device id is device.json's. Nothing is refreshed, nothing signs in, and
 * device.json is only read.
