Add /drone/devices endpoint that enumerates available WiFi interfaces
(via iw/iwconfig) and RTL-SDR devices (via SDRFactory.detect_devices),
matching the pattern used by TSCM.
Sidebar WiFi interface and RTL-SDR inputs are now <select> elements
populated on init() from /drone/devices, consistent with how other
modes expose hardware selection. HackRF checkbox remains as a toggle
since it's a binary capability rather than an enumerated device list.

Data pipeline (critical): scanners/detectors now write to a separate _obs_queue;
a relay thread reads observations and calls correlator.process(), which emits
processed DroneContact dicts to drone_queue for SSE. Without this the SSE stream
received raw unserializable dataclass objects causing JSON errors.
Frontend (critical):
- Add droneContactList container to drone.html so contact cards render
- Add droneMap container and initialize Leaflet in drone.js init()
- Define dsc-distress-pulse keyframes in drone.css (was referenced but missing)
- Fix SSE reconnect: null _sse before setTimeout to prevent _connectSSE no-op loop
Other fixes:
- Validate rtl_sdr_index with validate_device_index(), return 400 on bad input
- Move _ensure_workers() inside _drone_lock to prevent double-initialization race
- Add double-call guard to RemoteIDScanner.start()

Concurrent POST /drone/start under gevent would race on _drone_running;
lock mirrors the ais_lock / dsc_lock pattern used throughout the codebase.
Null guards prevent AttributeError if worker constructors fail.

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.
