Kristoffer Dalby 0288614bdf hscontrol: add servertest harness for in-process control plane testing ...

Add a new hscontrol/servertest package that provides a test harness
for exercising the full Headscale control protocol in-process, using
Tailscale's controlclient.Direct as the client.

The harness consists of:
- TestServer: wraps a Headscale instance with an httptest.Server
- TestClient: wraps controlclient.Direct with NetworkMap tracking
- TestHarness: orchestrates N clients against a single server
- Assertion helpers for mesh completeness, visibility, and consistency

Export minimal accessor methods on Headscale (HTTPHandler, NoisePublicKey,
GetState, SetServerURL, StartBatcher, StartEphemeralGC) so the servertest
package can construct a working server from outside the hscontrol package.

This enables fast, deterministic tests of connection lifecycle, update
propagation, and network weather scenarios without Docker.
