feat: add verify client config for embedded DERP (#2260)

* feat: add verify client config for embedded DERP

* refactor: embedded DERP no longer verify clients via HTTP

- register the `headscale://` protocol in `http.DefaultTransport` to intercept network requests
- update configuration to use a single boolean option `verify_clients`

* refactor: use `http.HandlerFunc` for type definition

* refactor: some renaming and restructuring

* chore: some renaming and fix lint

* test: fix TestDERPVerifyEndpoint

- `tailscale debug derp` use random node private key

* test: add verify clients integration test for embedded DERP server

* fix: apply code review suggestions

* chore: merge upstream changes

* fix: apply code review suggestions
