Fix container startup crash caused by honcho 1.1.0 + setuptools 82.x incompatibility

[Copilot]

honcho 1.1.0 imports from pkg_resources import iter_entry_points, which fails with ModuleNotFoundError after setuptools 82.0.0 removed pkg_resources from the venv. Since the Dockerfile runs pip install -U pip setuptools, fresh builds started getting setuptools 82.x and the container exited with code 1 immediately on startup.

Changes

• requirements.txt: honcho 1.1.0 → 2.0.0 — v2 uses importlib.metadata instead of pkg_resources
• opbeans/settings.py:
  • Replace deprecated structlog.threadlocal.wrap_dict(dict) with context_class=dict + add structlog.contextvars.merge_contextvars processor (modern structlog API since 21.2.0)
  • Keep elasticapm.contrib.django.handlers.LoggingHandler to preserve original logging behavior
  • Remove USE_L10N = True (dropped in Django 5.0)
• opbeans/tasks.py: Replace except TransportError as e: if e.status_code == 404 with except NotFoundError — TransportError.status_code doesn't exist in elasticsearch-py 8.x
• opbeans/__init__.py: Remove default_app_config (ignored since Django 3.2, removed in 5.0)

Copilot is right that this is deprecated but I would like to not change behavior

@copilot take into account this comment #529 (comment)

[Copilot]

Restored the elasticapm handler and updated the opbeans logger to use ['console', 'elasticapm'] again in commit 6636788. The original logging behavior is preserved.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• metadata.google.internal
  • Triggering command: /usr/bin/python python manage.py check (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
