f50043f6cb tka,types/key: remove dependency for tailcfg & types/ packages on tka
Following the pattern elsewhere, we create a new tka-specific types package for the types
that need to couple between the serialized structure types, and tka.

tsconnect: add flag to specify control server (#5294)
To improve the local development experience, this change allows a
control url to be passed in with the `--dev-control=` flag.

If the flag is passed in when not specifying dev, an error is returned.

If no flag is passed, the default remains the Tailscale controlled
control server set by `ipn.DefaultControlURL`.

4001d0bf25 assorted: plumb tka initialization & network-lock key into tailscaled
- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
 - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

9a2171e4ea cmd/tsconnect: make terminal resizable
Makes the terminal container DOM node as large as the window (except for
the header) via flexbox. The xterm.js terminal is then sized to fit via
xterm-addon-fit. Once we have a computed rows/columns size, and we can
tell the SSH session of the computed size.

Required introducing an IPNSSHSession type to allow the JS to control
the SSH session once opened. That alse allows us to programatically
close it, which we do when the user closes the window with the session
still active.

I initially wanted to open the terminal in a new window instead (so that
it could be resizable independently of the main window), but xterm.js
does not appear to work well in that mode (possibly because it adds an
IntersectionObserver to pause rendering when the window is not visible,
and it ends up doing that when the parent window is hidden -- see
xtermjs/xterm.js@87dca56dee)

617a2ec7cc cmd/tsconnect: add Tailwind CSS support and switch to using it
Integrates Tailwind CSS as an esbuild plugin that invokes the CLI
to process the input. It takes ~400ms, so it seems like the easiest
option (vs running a separate process for dev mode).

Existing minimal look and feel is replicated with Tailwind classes,
mostly to prove that the entire system works, including unused
class removal.

Also fixes yarn warnings about package.json not having a license
(which were showing up when invoking any scripts).

cmd/gitops-pusher: add etag cache file for the three version problem (#5124)
This allows gitops-pusher to detect external ACL changes. I'm not
sure what to call this problem, so I've been calling it the "three
version problem" in my notes. The basic problem is that at any given
time we only have two versions of the ACL file at any given point:
the version in CONTROL and the one in the git repo. In order to
check if there has been tampering of the ACL files in the admin
panel, we need to have a _third_ version to compare against.

In this case I am not storing the old ACL entirely (though that could
be a reasonable thing to add in the future), but only its sha256sum.
This allows us to detect if the shasum in control matches the shasum
we expect, and if that expectation fails, then we can react
accordingly.

This will require additional configuration in CI, but I'm sure that
can be done.

b763a12331 cmd/tsconnect: allow building static resources in a different directory
When using tsconnect as a module in another repo, we cannot write to
the ./dist directory (modules directories are read-only by default -
there is a -modcacherw flag for `go get` but we can't count on it).

We add a -distdir flag that is honored by both the build and serve
commands for where to place output in.

Somewhat tedious because esbuild outputs paths relative to the working
directory, so we need to do some extra munging to make them relative
to the output directory.

6f5096fa61 cmd/tsconnect: initial scaffolding for Tailscale Connect browser client
Runs a Tailscale client in the browser (via a WebAssembly build of the
wasm package) and allows SSH access to machines. The wasm package exports
a newIPN function, which returns a simple JS object with methods like
start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh
package is used for the SSH client.

Terminal emulation and QR code renedring is done via NPM packages (xterm
and qrcode respectively), thus we also need a JS toolchain that can
install and bundle them. Yarn is used for installation, and esbuild
handles loading them and bundling for production serving.
