Producing a real alert to check the wiring showed #47 twice in one Events row:
once as the badge the browser draws from the `number` field, and again at the
start of the message, because the number had been prefixed onto the shared
string.
ntfy carries plain text and has nowhere else to put a number or a timestamp, so
those belong in a push body built for it. The browser already receives `number`
and `at` as fields and formats its own local time, so its message stays clean.
Alert now carries both: `message` for a screen, `push` for a phone.
