Radiosonde route now runs a quick import check before launching the full
subprocess, catching missing Python dependencies immediately with a clear
message instead of a truncated traceback. Error messages are context-aware:
import errors suggest re-running setup.sh rather than checking SDR connections.
Increased stderr truncation limit from 200 to 500 chars and added full stderr
logging via logger.error() across all affected routes (radiosonde, ais, aprs,
acars, vdl2) for easier debugging.

SSE EventSource connections for AIS, ACARS, VDL2, and radiosonde were
not closed when switching modes, causing fd exhaustion after repeated
switches. Also fixes socket leaks on exception paths in AIS/ADS-B
stream parsers, closes subprocess pipes in safe_terminate/cleanup, and
caches skyfield timescale at module level to avoid per-request fd churn.

The registry used plain int keys (device index), so HackRF at index 0
and RTL-SDR at index 0 would collide. Changed to composite string keys
("sdr_type:index") so each SDR type+index pair is tracked independently.
Updated all route callers, frontend device selectors, and session restore.

When dashboards (satellite, ADS-B, AIS) are loaded via iframe with
?embedded=true, the full navigation bar was still rendered, creating
a "UI in UI" effect. Pass the embedded query param from route handlers
to templates and conditionally skip the nav include.

Adds a unified analytics mode under the Security nav group that aggregates
data across all signal modes. Includes emergency squawk alerting (7700/7600/7500),
vertical rate anomaly detection, ACARS/VDL2-to-ADS-B flight correlation,
geofence zones with enter/exit detection for aircraft/vessels/APRS stations,
temporal pattern detection, RSSI history tracking, Meshtastic topology mapping,
and JSON/CSV data export.

Implements centralized tracking of SDR device allocation to prevent
multiple decoders from trying to use the same device simultaneously.
- Add sdr_device_registry with claim/release/status functions in app.py
- Update all SDR-based routes to claim devices on start and release on stop
- Return HTTP 409 with DEVICE_BUSY error when device is already in use
- Clear registry on /killall
- Skip device claims for remote connections (rtl_tcp, remote SBS)
