style: use #[expect] instead of #[allow]

[tangowithfoxtrot]

📔 Objective

Rust 1.81 stabilized the #[expect] attribute. This attribute acts very similarly to #[allow], in that it allows for the suppression of various style lints. Unlike #[allow], however, it tells the linter to expect that you are overriding a linter warning. If the override is no longer applicable, then #[expect] will throw a warning stating that the lint suppression is no longer needed so that you can remove it.
