Set MSRV to 1.75, remove #[async_trait] declarations whenever possible

Axum still uses `async_trait`, let them do whatever they want. I will
no longer be subject to the humiliation of trying to dig through
lifetime errors and unreadable declarations. Also I don't fucking care
about MSRV, I'm not a library. If you don't have modern Rust, get one.
