Adds two Gokrazy-based vmtests covering the tailscaled web client at
port 5252:
* TestWebClientLocalAccess enables the web client on a single node
and exercises the canonical owner session flow against the node's
own Tailscale IP: an unauthenticated GET /api/auth that identifies
the caller, a GET /api/auth/session/new that issues a
TS-Web-Session cookie, and a final GET /api/auth that reports
authorized=true with the cookie.
* TestWebClientRemoteAccess runs the same session flow from a peer
node on the same tailnet against a second target node's web
client, exercising netstack interception of incoming :5252
traffic, cross-node WhoIs, and the same-user "owner" path. It
then flips the test control server's AllNodesSameUser off,
re-logs in the client under a fresh identity, and asserts that
GET /api/auth/session/new returns 401 with body "not-owner" --
exercising the cross-user rejection in client/web/auth.go.
To make the natlab test environment exercise the same code path
as production (check mode, where the web client posts to
/machine/webclient/init via Noise and waits on a control-issued
auth URL), this also:
* Allowlists the natlab fake control hostname "control.tailscale"
in client/web/auth.go's controlSupportsCheckMode so the web
client follows the check-mode branch rather than the
no-check-mode shortcut that immediately marks new sessions
authenticated.
* Adds /machine/webclient/{init,wait} handlers to testcontrol.
init returns a placeholder auth ID and URL; wait returns
Complete=true immediately, so the web client's awaitUserAuth
resolves on its first call. Together these let the tests drive
the full check-mode session lifecycle without a real
browser-click loop.
To support the multi-request HTTP flows from the test harness,
this also adds:
* vmtest.Env.HTTPGetStatus, a sister of HTTPGet that returns the
upstream status code, body, and Set-Cookie cookies (as a
vmtest.HTTPResponse) and accepts cookies on the outgoing
request, so tests can drive flows that depend on cookie
continuity.
* Cookie pass-through in cmd/tta's /http-get handler: it forwards
the Cookie request header upstream and surfaces upstream
Set-Cookie response headers downstream. This is what lets
HTTPGetStatus carry a session cookie across requests.
Previously the only tests of the web client were in-process
httptest-based handler tests in client/web/web_test.go; nothing
exercised the actual port 5252 listener wiring, the cross-node
auth path, cookie-driven session state transitions through the
check-mode control round-trip, or the not-owner rejection end
to end.
