Subject: [PATCH] =?UTF-8?q?=F0=9F=94=87(backend)=20silence=20expected=2040?=
 =?UTF-8?q?1=20warnings=20on=20/me?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On a busy morning, `/me` alone produced 72k warning logs — 97% of
all warnings. They all come from anonymous requests to `/me`
without credentials, which is normal: `/me` is how the app
determines the current auth status.

These warnings carry no diagnostic value on this endpoint, so
silence them there to cut down on log volume.
