/**
 * v1.4.47.6 — per-channel APNs test endpoint.
 *
 * Mirrors `/api/notifications/web-push/test`: fires a single self-test
 * push to the calling user's iOS devices via `sendViaApns`. The
 * `notification-status-card` UI on the Settings page maps the
 * "Test senden" button on the APNS channel row to this endpoint.
 *
 * Why a separate endpoint per channel instead of `/api/admin/notifications/test`:
 * - The admin test endpoint requires admin role; the per-channel test
 *   is available to any authenticated user who owns the channel.
 * - The admin variant fans out to ALL channels at once; the per-channel
 *   variant lets the user verify a single channel after a fix without
 *   spamming the other channels too.
