🛠️ [TASK] : Remove expect() from the upstream Scylla crates FromRow derived macro

[stevenj]

Summary

Fix the upstream FromRow derived macro to not use expect.

Description

The Scylla Rust crate has expect() inside the derived macro FromRow.
It is possible for that function to return an error, which it should do rather than panic.
This task is to fix the macro to return an error, and not panic.
Then remove the #[allow(clippy::expect_used)] lint allowances from Catalyst gateway that were added to get a clean compilation.
