Final: Complete modernization - Option 1 deployment, unified persistence, migration scripts

- Implement Docker image-based deployment (Option 1)
  * Code immutable in image, no volume override
  * Eliminated init-data.sh manual step
  * Simplified deployment process

- Unified persistence in data/ folder
  * Moved nginx.conf and nginx-custom-domains.conf to data/
  * All runtime configs and data in single location
  * Clear separation: repo (source) vs data/ (runtime)

- Archive legacy features
  * Groups blueprint and templates removed
  * Legacy playlist routes redirected to content area
  * Organized in old_code_documentation/

- Added network migration support
  * New migrate_network.sh script for IP changes
  * Regenerates SSL certs for new IP
  * Updates database configuration
  * Tested workflow: clone → deploy → migrate

- Enhanced deploy.sh
  * Creates data directories
  * Copies nginx configs from repo to data/
  * Validates file existence before deployment
  * Prevents incomplete deployments

- Updated documentation
  * QUICK_DEPLOYMENT.md shows 4-step workflow
  * Complete deployment workflow documented
  * Migration procedures included

- Production ready deployment workflow:
  1. Clone & setup (.env configuration)
  2. Deploy (./deploy.sh)
  3. Migrate network (./migrate_network.sh if needed)
  4. Normal operations (docker compose restart)

-## 🚀 Quick Start (One Command)
+## 🚀 Complete Deployment Workflow
 
+### **1️⃣ Clone & Setup**
 ```bash
-cd /srv/digiserver-v2
-bash deploy.sh
+# Copy the app folder from repository
+git clone <repository>
+cd digiserver-v2
+
+# Copy environment file and modify as needed
+cp .env.example .env
+
+# Edit .env with your configuration:
+nano .env
 ```
 
-This will:
-1. ✅ Start Docker containers
-2. ✅ Initialize database
-3. ✅ Run migrations
-4. ✅ Configure HTTPS
-5. ✅ Display access information
+**Configure in .env:**
+```env
+SECRET_KEY=your-secret-key-change-this
+ADMIN_USERNAME=admin
+ADMIN_PASSWORD=your-secure-password
+DOMAIN=your-domain.com
+EMAIL=admin@your-domain.com
+IP_ADDRESS=192.168.0.111
+```
+
+---
+
+### **2️⃣ Deploy via Script**
+```bash
+# Run the deployment script
+./deploy.sh
+```
+
+This automatically:
+1. ✅ Creates `data/` directories (instance, uploads, nginx-ssl, etc.)
+2. ✅ Copies nginx configs from repo root to `data/`
+3. ✅ Starts Docker containers
+4. ✅ Initializes database
+5. ✅ Runs all migrations
+6. ✅ Configures HTTPS with SSL certificates
+7. ✅ Displays access information
+
+**Output shows:**
+- Access URLs (HTTP/HTTPS)
+- Default credentials
+- Next steps for configuration
+
+---
+
+### **3️⃣ Network Migration (When Network Changes)**
+
+When moving the server to a different network with a new IP:
+
+```bash
+# Migrate to the new network IP
+./migrate_network.sh 10.55.150.160
+
+# Optional: with custom hostname
+./migrate_network.sh 10.55.150.160 digiserver-secured
+```
+
+This automatically:
+1. ✅ Regenerates SSL certificates for new IP
+2. ✅ Updates database HTTPS configuration
+3. ✅ Restarts nginx and app containers
+4. ✅ Verifies HTTPS connectivity
+
+---
+
+### **4️⃣ Normal Operations**
+
+**Restart containers:**
+```bash
+docker compose restart
+```
+
+**Stop containers:**
+```bash
+docker compose down
+```
+
+**View logs:**
+```bash
+docker compose logs -f
+```
+
+**View container status:**
+```bash
+docker compose ps
+```
