[fmt] match Omicron rust formatting for consistency + edition 2024

[zeeshanlakhani]

My editor complains when using 2024 edition enhancements, even though the min version here is Rust 1.90.

This PR aligns us with Omicron's formatting style (and edition).

This looks to generally condense things overall. I'm happy with it since it matches the decisions we've made in other repos.

I did attempt to verify the change on my Macbook to some extent:

So I have some divergence, but that lines up with some of the modules just not playing well on this platform. The diff itself does just look like, as reported, cargo fmt has bailed on those modules for me.

@FelixMcFelix I can't ignore those generated files, and it seems to be OSX only, as they can't build.
