fix: [#2831] remove --lazy-apps to unbreak OpenTelemetry setup in web

maykin_common.otel.setup_otel() detects uwsgi and defers its real
initialization to a uwsgidecorators.postfork hook -- correct for uWSGI's
default prefork model, but --lazy-apps loads the app in each worker
*after* it's already forked, so that hook has no future fork event to
attach to and never fires. OTel silently never initializes for this
process, dropping every metric/trace it would otherwise record, while
Celery (no uwsgi involved) exports fine -- which is why only
Celery-attributed data ever showed up.

--lazy-apps was added in 781af34 to fix Python 3.13 segfaults at the
fork boundary. Removing it trades that fix for working observability;
if the segfaults resurface, the better fix is teaching maykin_common to
skip the postfork deferral when uwsgi.opt indicates lazy-apps, rather
than reintroducing this.

Closes: #2831
