  }
  return forward.filter(fwd => fwd.nym || fwd.user?.name).map(fwd => ({ nym: fwd.nym ?? fwd.user?.name, pct: Number(fwd.pct) }))
}
Normalize an array of forwards by converting the pct from a string to a number
Also extracts nym from nested user object, if necessary
@param {*} forward Array of forward objects ({nym?: string, pct: string, user?: { name: string } })
@returns normalized array, or undefined if not provided
