Fixes an issue where we will not correctly return the latest key by sequence number if the fetch returns them in a order where the latest key is not last. The db query uses `ORDER BY sequence DESC` it is likely we have been operating incorrectly.
Adds a second key to one of the test cases which fails without this fix.
Also includes some debug logging statements I found helpful while chasing key rotation issues.
- Adds `testutil.GoleakOptions` and consolidates existing options to
this location
- Pre-emptively adds required ignore for this Dependabot PR to pass CI

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.
