Consider moving chat fetching to client side

[AbdBarho]

nextjs randomly shows this in the console:

Warning: data for page "/chat/[id]" (path "/chat/222222-1111-1111-1111-11111111") is 449 kB which exceeds the threshold of 128 kB, this amount of data can reduce performance.
See more info here: https://nextjs.org/docs/messages/large-page-data

We should either move the fetching to the client, or try and compress the values. (although our server is already overloaded, compressing might make stuff worse).
