Panic safety script could be replaced with official tooling

[adpaco-aws]

Describe the improvement you'd like to request

@cdisselkoen noted that we could probably replace panic_safety.sh with the new clippy tools available in Rust 1.81 including the ability to do #[allow(clippy::expect_used, reason = "...")] and an option we can enforce on our workspace’s Cargo.toml to allow_attributes_without_reason = deny.

If this official tooling allows us to completely replace the panic safety script, we should do it.
