Add client to cookie domain

[hudson-newey]

At the moment our cookies have the domain api.ecosounds.org.

This means that when the client loads with the domain ecosounds.org, it doesn't have access to the api cookies such as _baw_session.

As part of QutEcoacoustics/workbench-client#1979, we need to pass through cookies so that SSR can make authenticated requests, but is not currently possible, because the HTTP request to the SSR server does not contain any of the api cookies needed for authentication.
