Fix Nix builds and update the lock file (#641)

* Fix clippy warnings

* Fix doc example

* Clean up tonic-web usage

It looks like `tonic_web::enable` was removed with the 0.13.x release so
this code hasn't actually compiled for a long time. The doc and code
examples all use a custom cors layer so whatever heavy lifting the 0.12
method was doing doesn't seem necessary anymore

* ci: run clippy with all features enabled

Features are additive so this should be safe to lint them all together
(and avoid the combinatorics of using cargo-hack)

* ci: run all crate tests in one invocation

1. We've already committed our lockfile so there's no need to test the
   API/subscriber crates individually (if we want to test with the
   latest available versions we should be running a `cargo update` in
   CI, so this change remains compatible with the previous behavior)
2. Also enable some non-default feature flags to ensure they are being
   tested

* Fix nix builds

* flake.lock: Update
