[katana] connection closed

[notV4l]

Describe the bug
i experienced this error multiple times while doing sozo migrate, seems to happen randomly

Caused by: Declaration of class failed: error sending request for url (http://localhost:5050/): connection closed before message completed error: script failed with exit code: ExitCode(unix_exit_status(1))

same error on torii side
ERROR torii::engine: Fetching data. error=error sending request for url (http://0.0.0.0:5050/): connection closed before message completed

When this error happen, its then impossible to close katana with ctrl+c, you have to kill -9

@kariy I could reproduce migrating spawn-and-move with:

cargo run --bin katana -r -- --dev --block-time 2000 --sequencing.block-max-cairo-steps 3000000

Seems related to when one transaction is exceeding the block size.
