This PR is [resolving the dispatch part of Coder
Inbocx](https://github.com/coder/internal/issues/403).
Since the DB layer has been merged - we now want to insert notifications
into Coder Inbox in parallel of the other delivery target.
To do so, we push two messages instead of one using the `Enqueue`
method.
Refactors our use of `slogtest` to instantiate a "standard logger" across most of our tests. This standard logger incorporates https://github.com/coder/slog/pull/217 to also ignore database query canceled errors by default, which are a source of low-severity flakes.
Any test that has set non-default `slogtest.Options` is left alone. In particular, `coderdtest` defaults to ignoring all errors. We might consider revisiting that decision now that we have better tools to target the really common flaky Error logs on shutdown.
This PR aims to close#14253
We keep the default behavior using the Coder logo if there's no logo
set.
Otherwise we want to use the logo based on the URL set in appearance.

A bunch of notification tests create a whole `coderd`, when all they use is the database and logger. This makes the tests more expensive to run, and pollutes the test logs with a bunch of stuff that doesn't matter (e.g. tailnet).
