Components related to project usage costs have been updated to show
different estimations for each partner, and the satellite has been
updated to send the client the information it needs to do this.
Previously, project costs in the satellite frontend were estimated
using only the price model corresponding to the partner that the user
registered with. This caused users who had a project containing
differently-attributed buckets to see an incorrect price estimation.
