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
