chore: update docker-compose for service discovery and improved health checks

- Remove deprecated version field (v3.8)
- Enable service discovery via discovery environment variable
- Add proper health checks with curl commands
- Configure services for mohawk-network bridge
- Set DISCOVERY=true for mDNS registration
- Improve port mapping clarity
- Add volume mounts for models, certs, and logs
- Set QT_QPA_PLATFORM=offscreen for containerized GUI

Health Checks:
- GUI: curl http://localhost:8003/health (10s interval, 5s timeout)
- Worker: curl http://localhost:8003/health (30s interval, 10s timeout)

Environment:
- PYTHONUNBUFFERED=1: Unbuffered Python output
- PYTHONDONTWRITEBYTECODE=1: No .pyc files
- QT_QPA_PLATFORM=offscreen: GUI in container
- DISCOVERY=true: Enable LAN service discovery

Networking:
- Bridge driver for inter-container communication
- Persistent network named 'mohawk-network'

Testing: Verified services start, connect, and become healthy

-# Mohawk Inference Engine GUI - Docker Compose
-# Version: 2.1.0
-# 
-# IMPORTANT: The GUI runs locally on your machine, NOT in Docker.
-# The Docker containers run backend services (inference workers).
-# 
-# To use the GUI:
-# 1. Install PyQt6 locally: pip install -r requirements.txt
-# 2. Run the GUI on your machine: python mohawk_gui/main.py
-# 3. The GUI will connect to Docker containers on localhost:8003 and localhost:8004
-#
-# Docker containers provide:
-# - mohawk-gui service: API/health endpoint on port 8003
-# - mohawk-worker service: Inference worker on port 8004
