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 Co-authored-by: Madison Grubb <madison@elastiflow.com> Reviewed-on: #6
