CI clippy didn't emit warning about too large types that were found when running clippy locally

Issue にリンクされている CI 実行から始め、その clippy の呼び出しと Rust 1.77.2 toolchain を、警告を出力したローカルコマンドと比較します。rust/operator-binary/src/controller.rs の 638、792、1323 行を調査し、報告された result_large_err 警告に注目します。完了条件は、違いを説明し、適切であれば CI が同じ警告を報告することです。

When reviewing #614 I ran clippy locally and got the warnings pasted below, but CI running clippy did not alert on these https://github.com/stackabletech/nifi-operator/actions/runs/9003755958

Probably worth investigating why this differs at some point.

My local rust:

❯ cargo --version
cargo 1.77.2 (e52e36006 2024-03-26)

Version stated in ci: RUST_TOOLCHAIN_VERSION: "1.77.2"
