Steps to reproduce

1. Submit a run with a large repo diff (e.g. create a 50MB file)
2. Observe the run stuck in pulling and an error in the container logs:

time=2025-05-28T18:10:15.600273Z level=error msg=Unexpected API error err=[http.go:79 api.(*Server).uploadCodePostHandler] unexpected EOF

The problem may or may not occur depending on the network speed/state. Reduce the client timeout to reproduce it:

#2673 made it possible to configure upload code size limit, thus allowing for large uploads. unexpected EOF may happen due to the client dropping connection after the timeout (which is 9s now). Clearly, 9s is not sufficient for large uploads and should be increased (e.g. to 1m).
