Benoit Chesneau b19c648a67 fix: lazy import dirty module for gevent compatibility ...

Closes #3482

The dirty module (which uses asyncio and concurrent.futures) was being
imported at gunicorn startup via gunicorn.arbiter. This caused
concurrent.futures to be imported before user code could call
gevent.monkey.patch_all(), breaking gevent's monkey-patching.

Changes:
- gunicorn/arbiter.py: Import DirtyArbiter and set_dirty_socket_path
  lazily inside spawn_dirty_arbiter() instead of at module level
- gunicorn/dirty/worker.py: Import ThreadPoolExecutor lazily inside
  run() method instead of at module level
- Add tests/workers/test_gevent_import_order.py with 5 tests verifying:
  - concurrent.futures is NOT imported when gunicorn.arbiter loads
  - gevent patching works correctly with gunicorn
  - Reproduces the exact scenario from the bug report gist

This ensures gevent's monkey.patch_all() can run before concurrent.futures
is imported, allowing proper patching of threading primitives.
