- Fallback route to log the request and return 404 with a message
- Trace layer to print all request when tracing,
- use `webfinger-rs` to make dealing with webfinger responses in
axum easier and give us a nice builder for those responses
Note: `webfinger-rs` is pinned to a git release so it has an up
to date version of axum, nothing changed since last release but
dependency bumps.
