Upgrade to Rust 1.85 and Rust 2024 edition.

There are a couple of migration suggestions from `cargo fix --edition` that I have deliberately skipped, which are intended to make sure that the changes to `if let` scoping don't bite us. They don't, I'm pretty sure, and if I turn out to be wrong, I'd rather fix the scoping issues (as they arise) than use `match` (`cargo fix --edition`'s suggestion).

This change also includes a bulk reformat and a clippy cleanup.

NOTA BENE: As this requires a new Rust toolchain, you'll need to update Rust (`rustup update`, normally) or the server won't build. This also applies to the Debian builder Docker image; it'll need to be rebuilt (from scratch, pulling its base image again) as well.
