Updates and general fixes (#5762)

Updated all the crates to the latest version.
We can unpin mimalloc, since the musl issues have been fixed
Also fix a RUSTSEC https://osv.dev/vulnerability/RUSTSEC-2025-0023 for tokio

Fixed some clippy lints reported by nightly.

Ensure lints and are also run on the macro crate.
This resulted in some lints being triggered, which I fixed.

Updated some GHA uses.
