Re-implement servers in axum (mentimeter#94)

Major rewrite of both linkup servers to axum.

- Worker now uses axum for routing + native worker fetch for network
requests
- Local server now uses axum for routing + "native" hyper (no reqwest)
for network requests
- Adds server-tests to integration test both worker and local servers
