Subject: [PATCH] fix(analytics): the Track API payload field is 'name', not
 'event'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Second half of the envelope fix: ITrackPayload is {name, properties, profileId} — sending
'event' is rejected with 400 "payload/name Invalid input: expected string", which the
module swallows by design. Verified against packages/validation/src/track.validation.ts
and the SDK's track(name, properties) signature.
