Tailscale serve maintains a set of listeners so that serve traffic from
the local device can be properly served when running in kernel
networking mode. #10177 refactored that logic so that it could be reused
by the internal web client as well. However, in my refactoring I missed
actually calling the serve handler to handle the traffic.

In production, the asset handler is receiving requests for pages like
/details, which results in a 404. Instead, if we know the requested file
does not exist, serve the main index page and let wouter route it
appropriately on the frontend.

After logging in, the `?check=now` query string is still present if it
was passed. Reloading the page causes a new check mode to be triggered,
even though the user has an active session. Only trigger the automatic
check mode if the user is not already able to manage the device.

When we run tailscled under systemd, restarting the unit kills all child
processes, including "tailscale update". And during update, the package
manager will restart the tailscaled unit. Specifically on Debian-based
distros, interrupting `apt-get install` can get the system into a wedged
state which requires the user to manually run `dpkg --configure` to
recover.
To avoid all this, use `systemd-run` where available to run the
`tailscale update` process. This launches it in a separate temporary
unit and doesn't kill it when parent unit is restarted.
Also, detect when `apt-get install` complains about aborted update and
try to restore the system by running `dpkg --configure tailscale`. This
could help if the system unexpectedly shuts down during our auto-update.

Simply reading the taildrop directory can pop up security dialogs
on platforms like macOS. Avoid this by only performing garbage collection
of partial and deleted files after the first received taildrop file,
which would have prompted the security dialog window.

Use the `qpkg_cli` to check for updates and install them. There are a
couple special things about this compare to other updaters:
* qpkg_cli can tell you when upgrade is available, but not what the
version is
* qpkg_cli --add Tailscale works for new installs, upgrades and
reinstalling existing version; even reinstall of existing version
takes a while

The local web client has the same characteristic as tailscale serve, in
that it needs a local listener to allow for connections from the local
machine itself when running in kernel networking mode.
This change renames and adapts the existing serveListener to allow it to
be used by the web client as well.

io.Writer says you need to write completely on err=nil. (the result
int should be the same as the input buffer length)
We weren't doing that. We used to, but at some point the verbose
filtering was modifying buf before the final return of len(buf).
We've been getting lucky probably, that callers haven't looked at our
results and turned us into a short write error.

App connectors handle DNS requests for app domains over PeerAPI,
but a safety check verifies the requesting peer has at least permission
to send traffic to 0.0.0.0:53 (or 2000:: for IPv6) before handling the DNS
request. The correct filter rules are synthesized by the coordination server
and sent down, but the address needs to be part of the 'local net' for the
filter package to even bother checking the filter rules, so we set them here.
