fix(deps): remove deprecated tokio-process to resolve crossbeam/lock_api advisories

tokio-process 0.2 was pulling in old crossbeam-queue (<0.2.3),
crossbeam-utils (<0.8.7), and lock_api (<0.4.2) transitively. The code
already uses tokio::process::Command from the tokio crate directly, so
the tokio-process dependency was unused. Removing it eliminates all three
vulnerable transitive dependencies from svalinn, selur, vordr, and
cerro-torre services.
