feat(host/mgmt): mTLS auth — a paired client's cert authorizes the REST API
Phase 1 of moving the library off a manual mgmt token: the management API now serves
over HTTPS with the host's persistent identity (the cert clients already pin) and
OPTIONAL client-cert auth. A request is authorized if EITHER the peer presented a
client certificate whose SHA-256 is in the punktfunk/1 paired store (the same trust the
QUIC data plane uses — so a paired native client needs no token), OR it carries the
bearer token (the web console / admin). `/health` stays open.

axum-server can't surface the peer cert to a handler, so `serve_https` runs the rustls
handshake itself (tokio-rustls), reads the verified peer certificate, and serves the
axum Router over hyper with the fingerprint attached to each request; `require_auth`
checks it against `NativePairing::is_paired`. The verifier reuses the GameStream
AcceptAnyClientCert, parameterized to make client auth optional (a browser with no cert
still completes the handshake and falls back to the token).

Validated live: paired cert → 200, unpaired cert / no creds / bad token → 401, bearer
→ 200, /health open. (Note: the API is now HTTPS with a self-signed cert — a browser
shows a one-time trust prompt; native clients pin by fingerprint.)

Next: Apple client presents its identity over mTLS (drops the token field); embed the
web console; enable HTTPS mgmt by default.
