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.

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

When the /api/auth response indicates that synology auth is needed,
fetch the SynoToken and store it for future API calls. This doesn't yet
update the server-side code to set the new SynoAuth field.

This commit makes the following structural changes to the web
client interface. No user-visible changes.
1. Splits login, legacy, readonly, and full management clients into
their own components, and pulls them out into their own view files.
2. Renders the same Login component for all scenarios when the client
is not logged in, regardless of legacy or debug mode. Styling comes
from the existing legacy login, which is removed from legacy.tsx
now that it is shared.
3. Adds a ui folder to hold non-Tailscale-specific components,
starting with ProfilePic, previously housed in app.tsx.

Allows for serving the web interface from tailscaled, with the
ability to start and stop the server via localapi endpoints
(/web/start and /web/stop).
This will be used to run the new full management web client,
which will only be accessible over Tailscale (with an extra auth
check step over noise) from the daemon. This switch also allows
us to run the web interface as a long-lived service in environments
where the CLI version is restricted to CGI, allowing us to manage
certain auth state in memory.
ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for
ios builds to satisfy ios restriction from adding "text/template"
and "html/template" dependencies.

This commit makes two changes to the web client auth flow error
handling:
1. Properly passes back the error code from the noise request from
the localapi. Previously we were using io.Copy, which was always
setting a 200 response status code.
2. Clean up web client browser sessions on any /wait endpoint error.
This avoids the user getting in a stuck state if something goes
wrong with their auth path.

We already had a path on the web client server struct, but hadn't
plumbed it through to the CLI. Add that now and use it for Synology and
QNAP instead of hard-coding the path. (Adding flag for QNAP is
tailscale/tailscale-qpkg#112) This will allow supporting other
environments (like unraid) without additional changes to the client/web
package.
Also fix a small bug in unraid handling to only include the csrf token
on POST requests.

Instead of trying to use the user config dir, and then fail back to the
OS temp dir, just always use the temp dir. Also use a filename that is
less likely to cause collisions.
This addresses an issue on a test synology instance that was
mysteriously failing because there was a file at /tmp/tailscale. We
could still technically run into this issue if a
/tmp/tailscale-web-csrf.key file exists, but that seems far less likely.

This uses the new react-based web client for all builds, not just with
the --dev flag.
If the web client assets have not been built, the client will serve a
message that Tailscale was built without the web client, and link to
build instructions. Because we will include the web client in all of our
builds, this should only be seen by developers or users building from
source. (And eventually this will be replaced by attempting to download
needed assets as runtime.)
We do now checkin the build/index.html file, which serves the error
message when assets are unavailable. This will also eventually be used
to trigger in CI when new assets should be built and uploaded to a
well-known location.

node's own machine (i.e. came from the web client frontend). We'll

to the localapi, to protect against DNS rebinding attacks.

Synology and QNAP both run the web client as a CGI script. The old web
client didn't care too much about requests paths, since there was only a
single GET and POST handler. The new client serves assets on different
paths, so now we need to care.
First, enforce that the CGI script is always accessed from its full
path, including a trailing slash (e.g. /cgi-bin/tailscale/index.cgi/).
Then, strip that prefix off before passing the request along to the main
serve handler. This allows for properly serving both static files and
the API handler in a CGI environment. Also add a CGIPath option to allow
other CGI environments to specify a custom path.
Finally, update vite and one "api/data" call to no longer assume that we
are always serving at the root path of "/".

Add separate server methods for synology and qnap, and enforce
authentication and authorization checks before calling into the actual
serving handlers. This allows us to remove all of the auth logic from
those handlers, since all requests will already be authenticated by that
point.
Also simplify the Synology token redirect handler by using fetch.
Remove the SynologyUser from nodeData, since it was never used in the
frontend anyway.
