The root logger entry patch_log_config adds now uses INFO in dev and
WARNING in production (Python's default), so third-party library INFO
noise stays silent in production while subloggers remain free to
define their own level overrides. A user-supplied root level still
wins (setdefault).
staticfiles now logs via its own module logger instead of
uvicorn.error: the startup stats line shows in dev (root INFO) and is
hidden in production, and it no longer passes through the
uvicorn-quiet filter that silently ate it.
The kanta logger/handler/formatter block is removed: kanta configures
its own event loggers at import time as of its logging rework, and its
diagnostics follow the root logger like any other library.
