Collapses Start/StartHost/StartHostAuth onto StartServer(ServerConfig) so
auth and a TLS config can be set without growing the parameter list further.
When TLS is set the server presents the certificate and requires TLS on the
data plane; the wrappers preserve the existing no-auth/no-TLS behavior.

busauth.NewNkeyAuthenticator verifies a client's nkey signature over the
server nonce (decoding like nats-server: raw-url then std base64), maps the
nkey to its Ed25519 hex, and consults an injected IsAuthorized predicate.
Checking on every connection (rather than a static Options.Nkeys map) means
revoking a user denies its next connection with no restart. embeddednats
gains StartHostAuth(auth) and sets AlwaysEnableNonce so the server advertises
the nonce nkey clients need; Start/StartHost stay open (auth=nil) for dev.

Add a --bind flag (default 127.0.0.1) to membershipd that controls which
network interface both the control-plane HTTP API and the embedded NATS data
plane listen on. Use 0.0.0.0 to expose the stack to the LAN so remote peers
(phones, other PCs) can connect; keep the default for a loopback-only dev stack.
embeddednats gains StartHost(storeDir, host, port) for explicit interface
control; Start stays a backward-compatible wrapper (host "" = nats default
0.0.0.0) so the playground and tests are untouched.
