This change allows for an auth key to be specified as a url query param
for use in development mode. If an auth key is specified and valid, it
will authorize the client for use immediately.

Reduces the amount of boilerplate to render the UI and makes it easier to
respond to state changes (e.g. machine getting authorized, netmap changing,
etc.)
Preact adds ~13K to our bundle size (5K after Brotli) thus is a neglibible
size contribution. We mitigate the delay in rendering the UI by having a static
placeholder in the HTML.
Required bumping the esbuild version to pick up evanw/esbuild#2349, which
makes it easier to support Preact's JSX code generation.

This makes debugging easier, you can pass an AUMHash to a printf and get
a string that is easy to debug.
Also rearrange how directories/files work in the FS store: use the first
two characters of the string representation as the prefix directory, and
use the entire AUMHash string as the file name. This is again to aid
debugging: you can `ls` a directory and line up what prints out easily
with what you get from a printf in debug code.

The Do function assists in calling functions that must succeed.
It only interacts well with functions that return (T, err).
Signatures with more return arguments are not supported.

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.

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`.

Initialize logtail and provide an uploader that works in the
browser (we make a no-cors cross-origin request to avoid having to
open up the logcatcher servers to CORS).

4001d0bf25 caused tests in another repo to fail with a crash, calling

- 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).

JS -> native nodes worked already, tested by exposing a fetch() method
to JS (it's Promise-based to be consistent with the native fetch() API).
Native nodes -> JS almost worked, we just needed to set the LocalBackend
on the userspace netstack.

Avoids waterfalling of requests from the file (its load is triggered
from JavaScript).
Also has other cleanups to index.html, adding a <title> and moving the
<script> to being loaded sooner (but still not delaying page rendering
by using the defer attribute).

Changes Gzip and Brotli to optimize for speed instead of size. This
signficantly speeds up Brotli, and is useful when iterating locally
or running the build during a CI job (where we just care that it
can successfully build).

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)
