Logging: filter only the noisy progress poll from access log

Suppressing the whole uvicorn.access logger hid every request. Instead add a
logging.Filter that drops only /v1/loras/progress (polled ~1.5s by the web UI);
all other API request lines keep logging. A logger filter also survives uvicorn's
configure_logging(), which resets the access logger LEVEL at startup (that reset
is what defeated the earlier setLevel(WARNING)). --debug-web shows everything.
