Add comprehensive Digital Ocean deployment configuration for Cuoco API

[Copilot]

This PR adds complete deployment infrastructure to deploy the Cuoco API on Digital Ocean, optimized to maximize the use of $200 USD in credits.

Problem Solved

The project lacked deployment configuration files and documentation needed to deploy on Digital Ocean. The existing GitHub workflows referenced missing docker-compose files, and there was no guidance on how to leverage Digital Ocean credits effectively.

Solution Overview

Added a comprehensive deployment solution that enables:

• 30-minute deployment from zero to production
• 8+ months of hosting with $200 Digital Ocean credits
• Automated monitoring and backups
• Production-ready configuration with SSL, security, and scalability

Key Components Added

Docker Configuration

• docker-compose.yml - Production environment with MySQL 8.0, health checks, and persistent volumes
• docker-compose.dev.yml - Development environment with debugging-friendly settings
• .env.example - Complete template for all required environment variables

Deployment Automation

• scripts/deployment/setup-server.sh - One-command server setup script that installs Docker, Nginx, SSL certificates, and security hardening
• scripts/init-db.sql - Database initialization with proper UTF-8 encoding
• Updated GitHub workflows to use correct docker compose commands

Monitoring & Maintenance

• scripts/monitoring/health-check.sh - Comprehensive system health monitoring (API status, database connectivity, resource usage, SSL certificates)
• Automated daily backups at 2 AM
• Automated hourly health checks
• Log rotation and cleanup

Documentation Suite

• QUICK-START.md - 3-step deployment guide (30 minutes)
• DEPLOYMENT.md - Detailed deployment guide with multiple configuration options
• COST-CALCULATOR.md - Strategies to maximize $200 Digital Ocean credits
• DIGITAL-OCEAN-SUMMARY.md - Executive summary with architecture diagrams

Cost Optimization

The configuration provides multiple deployment strategies:

• Basic setup: $24/month = 8.3 months runtime
• Professional setup: $49/month = 4+ months runtime
• Enterprise setup: $85/month = 2.3 months runtime

Each tier includes detailed cost breakdowns and upgrade paths.

Production Features

• SSL-ready with Let's Encrypt integration
• Nginx reverse proxy with optimized settings for file uploads
• Health checks for all containers with automatic restart policies
• Persistent volumes for database and uploaded files
• Security hardening with UFW firewall and fail2ban
• Resource monitoring with alerting thresholds
• Automated backups with retention policies

Quick Deployment Process

1. Create Digital Ocean Droplet (Ubuntu 22.04, $24/month)
2. Run automated setup script: curl -fsSL https://raw.githubusercontent.com/MaxiHubb2/cuoco-api/main/scripts/deployment/setup-server.sh | bash
3. Clone repo, configure environment, and start: docker compose up -d --build

Testing

• Validated docker-compose.yml configuration syntax
• Tested build process with existing Dockerfile
• Verified all environment variables are properly templated
• Confirmed script compatibility with Ubuntu 22.04

This deployment configuration transforms the Cuoco API from a development project into a production-ready service that can be deployed and maintained with minimal effort while maximizing Digital Ocean credit value.
