This change updates log messaging when cleaning up wireguard only peers.
This change also stops us unnecessarily attempting to clean up disco
pings for wireguard only endpoints.

Previously had HMR websocket set to run from a different port
than the http proxy server. This was an old setting carried over
from the corp repo admin panel config. It's messing with hot
reloads when run from the tailscaled web client, as it keeps
causing the full page to refresh each time a connection is made.
Switching back to the default config here fixes things.

In prep for making mapSession's lifetime not be 1:1 with a single HTTP
response's lifetime, this moves the inactivity timer watchdog out of
mapSession and into the caller that owns the streaming HTTP response.
(This is admittedly closer to how it was prior to the mapSession type
existing, but that was before we connected some dots which were
impossible to even see before the mapSession type broke the code up.)

It was a really a mutable field owned by mapSession that we didn't move
in earlier commits.
Once moved, it's then possible to de-func-ify the code and turn it into
a regular method rather than an installed optional hook.
Noticed while working to move map session lifetimes out of
Direct.sendMapRequest's single-HTTP-connection scope.

Don't return CSP headers in dev mode, since that includes a bunch of
extra things like the vite server.
Allow images from any source, which is needed to load user profile
images.
Allow 'unsafe-inline' for various inline scripts and style react uses.
We can eliminate this by using CSP nonce or hash values, but we'll need
to look into the best way to handle that. There appear to be several
react plugins for this, but I haven't evaluated any of them.

3d7fb6c21d dropped the explicit called to (*Client).connect when
its (*Client).WatchConnectionChanges got removed+refactored.
This puts it back, but in RunWatchConnectionLoop, before the call
to the (*Client).ServerPublicKey accessor, which is documented to
return the zero value (which is what broke us) on an unconnected
connection.
Plus some tests.

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.

(*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.

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.

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).

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

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.
