fix(egressRecord): Remove unnecessary multiplication for ts conversion (

#1588)

### Context
This PR fixes the handling of the `servedAt` timestamp in the
`packages/upload-api/src/space/record.js` file.

The previous implementation included a multiplication by 1000, assuming
a conversion from seconds to milliseconds was necessary. This change
removes the conversion.
