/**
 * Create a Signature Event. Reuses the exact same `EventForm` as
 * `/admin/events/new`, with two additions:
 *  - the organizer picker is pre-scoped to Kolabora Official
 *    (`getUsers({ official: true })`) so the event also satisfies the
 *    legacy single-event "Kolabora Official showcase" rule
 *    (`is_signature_event`/`assertSignatureEvent()`), which is required to
 *    call the signature-profile endpoint below without touching that guard;
 *  - `attachSignatureProfile` has the form attach a blank `signature_profile`
 *    row right after creating the event, since presence of that row — not
 *    the organizer — is what actually makes it show up under
 *    `/admin/signature/events` (see Admin\EventController::index()'s
 *    `signature` filter).
