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

# Share Live
Stream your phone's camera and location to KestrelOS. Appears as a **live session** on the map and in **Cameras**. Uses **WebRTC** (Mediasoup) and requires **HTTPS** on mobile.
## Usage
1. Open **Share live** (sidebar → **Share live** or `/share-live`)
2. Tap **Start sharing**, allow camera/location permissions
3. Device appears on map and in **Cameras**
4. Tap **Stop sharing** to end
**Permissions:** Admin/leader can start sharing. All users can view live sessions.
## Requirements
- **HTTPS** (browsers require secure context for camera/geolocation)
- **Camera and location permissions**
- **WebRTC ports:** UDP/TCP `40000-49999` open on server
## Local Development
**Generate self-signed cert:**
```bash
chmod +x scripts/gen-dev-cert.sh
./scripts/gen-dev-cert.sh 192.168.1.123 # Your LAN IP
npm run dev
```
**On phone:** Open `https://192.168.1.123:3000`, accept cert warning, sign in, use Share live.
## WebRTC Configuration
- Server auto-detects LAN IP for WebRTC
- **Docker/multiple NICs:** Set `MEDIASOUP_ANNOUNCED_IP` to client-reachable IP/hostname
- **"Wrong host" error:** Use same URL on phone/server, or set `MEDIASOUP_ANNOUNCED_IP`
## Troubleshooting
| Issue | Fix |
|-------|-----|
| "HTTPS required" | Use `https://` (not `http://`) |
| "Media devices not available" | Ensure HTTPS and browser permissions |
| "WebRTC: failed" / "Wrong host" | Set `MEDIASOUP_ANNOUNCED_IP`, open firewall ports `40000-49999` |
| Stream not visible | Check server reachability and firewall |
