major: kestrel is now a tak server (#6)

## Added

- CoT (Cursor on Target) server on port 8089 enabling ATAK/iTAK device connectivity
- Support for TAK stream protocol and traditional XML CoT messages
- TLS/SSL support with automatic fallback to plain TCP
- Username/password authentication for CoT connections
- Real-time device position tracking with TTL-based expiration (90s default)
- API endpoints: `/api/cot/config`, `/api/cot/server-package`, `/api/cot/truststore`, `/api/me/cot-password`
- TAK Server section in Settings with QR code for iTAK setup
- ATAK password management in Account page for OIDC users
- CoT device markers on map showing real-time positions
- Comprehensive documentation in `docs/` directory
- Environment variables: `COT_PORT`, `COT_TTL_MS`, `COT_REQUIRE_AUTH`, `COT_SSL_CERT`, `COT_SSL_KEY`, `COT_DEBUG`
- Dependencies: `fast-xml-parser`, `jszip`, `qrcode`

## Changed

- Authentication system supports CoT password management for OIDC users
- Database schema includes `cot_password_hash` field
- Test suite refactored to follow functional design principles

## Removed

- Consolidated utility modules: `authConfig.js`, `authSkipPaths.js`, `bootstrap.js`, `poiConstants.js`, `session.js`

## Security

- XML entity expansion protection in CoT parser
- Enhanced input validation and SQL injection prevention
- Authentication timeout to prevent hanging connections

## Breaking Changes

- Port 8089 must be exposed for CoT server. Update firewall rules and Docker/Kubernetes configurations.

## Migration Notes

- OIDC users must set ATAK password via Account settings before connecting
- Docker: expose port 8089 (`-p 8089:8089`)
- Kubernetes: update Helm values to expose port 8089

+# Map and Cameras
+
+KestrelOS shows a **map** with devices, POIs, live sessions (Share live), and ATAK/iTAK positions. Click markers or use **Cameras** page to view streams.
+
+## Map Layers
+
+- **Devices** - Fixed feeds (IPTV, ALPR, CCTV, NVR, etc.) added via API
+- **POIs** - Points of interest (admin/leader can edit)
+- **Live sessions** - Mobile devices streaming via Share live
+- **CoT (ATAK/iTAK)** - Amber markers for connected TAK devices (position only)
+
+## Cameras
+
+A **camera** is either:
+1. A **device** - Fixed feed with stream URL
+2. A **live session** - Mobile device streaming via Share live
+
+View via map markers or **Cameras** page (sidebar).
+
+## Device Types
+
+| device_type | Use case |
+|-------------|----------|
+| `alpr`, `nvr`, `doorbell`, `feed`, `traffic`, `ip`, `drone` | Labeling/filtering |
+
+**source_type:** `mjpeg` (MJPEG over HTTP) or `hls` (HLS `.m3u8` playlist)
+
+Stream URLs must be `http://` or `https://`.
+
+## API: Devices
+
+**Create:** `POST /api/devices` (admin/leader)
+```json
+{
+  "name": "Main gate ALPR",
+  "device_type": "alpr",
+  "lat": 37.7749,
+  "lng": -122.4194,
+  "stream_url": "https://alpr.example.com/stream.m3u8",
+  "source_type": "hls"
+}
+```
+
+**List:** `GET /api/devices`  
+**Update:** `PATCH /api/devices/:id`  
+**Delete:** `DELETE /api/devices/:id`
+
+**Cameras endpoint:** `GET /api/cameras` returns devices + live sessions + CoT entities.
+
+## POIs
+
+Admins/leaders add/edit from **POI** page (sidebar). POIs appear as map pins (reference only, no stream).
