Adds a `redis.username` config option.
Details:
A `username` without a `password` (or `password_path`) is refused at
startup. Redis has no wire form for a username without a password, and
txredisapi only sends `AUTH` when a password is set, so the username
would otherwise be silently ignored. An explicitly empty password is
accepted, since that is how a `nopass` ACL user is configured.
This relies on txredisapi 1.4.12, the first release to accept a
`username` kwarg. That upstream support was contributed by @karolyi
specifically to unblock this.
Fixes#19238.

I thought ruff check would also format, but it doesn't.
This runs ruff format in CI and dev scripts. The first commit is just a
run of `ruff format .` in the root directory.
During the migration the automated script to update the copyright
headers accidentally got rid of some of the existing copyright lines.
Reinstate them.
Part of #9744
Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now.

This is done by creating a custom `RedisFactory` subclass that
periodically pings all connections in its pool.
We also ensure that the `replyTimeout` param is non-null, so that we
timeout waiting for the reply to those pings (and thus triggering a
reconnect).
This expands the current shadow-banning feature to be usable via
the admin API and adds documentation for it.
A shadow-banned users receives successful responses to their
client-server API requests, but the events are not propagated into rooms.
Shadow-banning a user should be used as a tool of last resort and may lead
to confusing or broken behaviour for the client.
We forgot to set the password on the subscriber connection, as well as
not calling super methods for overridden connectionMade/connectionLost
functions.
