Will Norris 6b956b49e0 client/web: add some security checks for full client
Require that requests to servers in manage mode are made to the
Tailscale IP (either ipv4 or ipv6) or quad-100. Also set various
security headers on those responses.  These might be too restrictive,
but we can relax them as needed.

Allow requests to /ok (even in manage mode) with no checks. This will be
used for the connectivity check from a login client to see if the
management client is reachable.

Aaron Klotz fbc18410ad ipn/ipnauth: improve the Windows token administrator check
(*Token).IsAdministrator is supposed to return true even when the user is
running with a UAC limited token. The idea is that, for the purposes of
this check, we don't care whether the user is *currently* running with
full Admin rights, we just want to know whether the user can
*potentially* do so.

We accomplish this by querying for the token's "linked token," which
should be the fully-elevated variant, and checking its group memberships.

We also switch ipn/ipnserver/(*Server).connIsLocalAdmin to use the elevation
check to preserve those semantics for tailscale serve; I want the
IsAdministrator check to be used for less sensitive things like toggling
auto-update on and off.

Fixes #10036

Sonia Appasamy e5dcf7bdde client/web: move auth session creation out of /api/auth
Splits auth session creation into two new endpoints:

/api/auth/session/new - to request a new auth session

/api/auth/session/wait - to block until user has completed auth url

Will Norris 658971d7c0 ipn/ipnlocal: serve web client on quad100 if enabled
if the user pref and nodecap for the new web client are enabled, serve
the client over requests to 100.100.100.100.  Today, that is just a
static page that lists the local Tailcale IP addresses.

For now, this will render the readonly full management client, with an
"access" button that sends the user through check mode.  After
completing check mode, they will still be in the read-only view, since
they are not accessing the client over Tailscale.

Instead, quad100 should serve the lobby client that has a "manage"
button that will open the management client on the Tailscale IP (and
trigger check mode). That is something we'll fix in a subsequent PR in
the web client code itself.

Sonia Appasamy 191e2ce719 client/web: add ServerMode to web.Server
Adds a new Mode to the web server, indicating the specific
scenario the constructed server is intended to be run in. Also
starts filling this from the cli/web and ipn/ipnlocal callers.

From cli/web this gets filled conditionally based on whether the
preview web client node cap is set. If not set, the existing
"legacy" client is served. If set, both a login/lobby and full
management client are started (in "login" and "manage" modes
respectively).

Will Norris 4ce4bb6271 client/web: limit authorization checks to API calls
This completes the migration to setting up authentication state in the
client first before fetching any node data or rendering the client view.

Notable changes:
 - `authorizeRequest` is now only enforced on `/api/*` calls (with the
   exception of /api/auth, which is handled early because it's needed to
   initially setup auth, particularly for synology)
 - re-separate the App and WebClient components to ensure that auth is
   completed before moving on
 - refactor platform auth (synology and QNAP) to fit into this new
   structure. Synology no longer returns redirect for auth, but returns
   authResponse instructing the client to fetch a SynoToken

Aaron Klotz 47019ce1f1 cmd/tailscaled: pre-load wintun.dll using a fully-qualified path
In corp PR #14970 I updated the installer to set a security mitigation that
always forces system32 to the front of the Windows dynamic linker's search
path.

Unfortunately there are other products out there that, partying like it's
1995, drop their own, older version of wintun.dll into system32. Since we
look there first, we end up loading that old version.

We can fix this by preloading wintun using a fully-qualified path. When
wintun-go then loads wintun, the dynamic linker will hand it the module
that was previously loaded by us.
