Allow to use Operations and APIs when prerendering

[cprecioso]

When using prerender: true, our APIs and Operations do not work in the server, only in the client.
This makes it so that people can't effectively prerender dynamic data in their apps.
We should find a way to make useQuery(myQuery) etc to work seamlessly in prerendered apps.
In wasp start the server is already running so it's simpler, but in wasp build the server does not run when building the client, so it might be trickier.

Main problem: if running the build locally, the data that the operations and APIs will have access to, is the local data, not the production database. Maybe it makes sense to delay this until we have Dynamic SSR and we render it in the production server.

Otherwise, people using external data sources can query them directly in their code by using if (import.meta.env.SSR) and a suspense-enabled fetching library
