feat(drone): add Flask blueprint, register routes, wire drone_queue

Implements Task 5: creates routes/drone.py with /status, /contacts,
/start, /stop, and /stream (SSE fanout) endpoints; registers the
drone_bp blueprint in routes/__init__.py; adds drone_queue to app.py;
adds opendroneid>=1.0 to requirements.txt. All 39 drone tests pass.
