Add Docker Support with Integrated OpenSquat

Hi... I've added comprehensive Docker support to make PhishGuard deployment much easier.

What's Changed

• One-command deployment: docker-compose up -d and you're done!
• OpenSquat auto-included: No more manual OpenSquat installation - it's baked into the Docker image
• Production ready: Proper Gunicorn config, health checks, security hardening
• Port conflict fix: Uses 8080:5000 mapping to avoid common port 5000 conflicts [This was my setup issue. You can change the port]

Why This Matters

Before: Users had to manually install OpenSquat, manage Python deps, deal with version conflicts, etc. Pretty painful for SOC teams who just want to get monitoring up fast.

After: git clone → docker-compose up -d → done. Takes 2-3 minutes instead of 30-60.

Files Changed

• Dockerfile - Multi-stage build with OpenSquat integration
• docker-compose.yml - Complete orchestration setup
• opensquat_integration.py - Smart path detection for Docker vs manual installs
• app.py - Fixed Gunicorn compatibility
• README.md - Added Docker deployment docs

Tested

✅ Builds successfully (~4 min build time)
✅ Container starts healthy and OpenSquat is detected
✅ Web interface works at http://localhost:8080
✅ Real-time monitoring functional
✅ Backward compatible with manual installs

Impact

This transforms PhishGuard from "developer tool requiring setup" to "enterprise-ready security appliance" that deploys instantly. Should significantly boost adoption by removing deployment friction.

The Docker implementation follows best practices (non-root user, health checks, proper signal handling) and is ready for production use.
