Logging overhaul part 2

[jrozner]

This is dependent on #1191. We should be able to rip out most of the helpers and simplify the logging based on setting the system logger and switching to context.Context aware logging methods. We'll likely want to plumb the context.Context through more of the application, especially into the database layer. This is something that go-kit/logging didn't have but log/slog does out of the box and that wasn't as tied into the http framework.
