feat: improve line items layout, number inputs and supplier click-to-call

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.
