Add Oracle Aggregator and CCIP Integration

- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control.
- Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities.
- Created .gitmodules to include OpenZeppelin contracts as a submodule.
- Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment.
- Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks.
- Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring.
- Created scripts for resource import and usage validation across non-US regions.
- Added tests for CCIP error handling and integration to ensure robust functionality.
- Included various new files and directories for the orchestration portal and deployment scripts.

+# Deploy Phase 2 from Nginx Proxy Host
+
+## Quick Start
+
+**You need to SSH to the proxy host first. The proxy may use a different SSH key.**
+
+### Step 1: SSH to Nginx Proxy
+
+```bash
+# Try with different keys if available:
+ssh besuadmin@20.160.58.99
+
+# Or with a specific key:
+ssh -i /path/to/proxy/key besuadmin@20.160.58.99
+```
+
+### Step 2: Copy Project Files to Proxy (if needed)
+
+**From your local machine**, after SSH access is working:
+
+```bash
+cd /home/intlc/projects/smom-dbis-138
+
+# Copy project to proxy (adjust key path as needed)
+rsync -avz -e "ssh -i /path/to/proxy/key" \
+  --exclude '.git' \
+  --exclude '.terraform' \
+  --exclude '*.tfstate*' \
+  --exclude '.terraform.lock.hcl' \
+  --exclude 'terraform.tfvars' \
+  --exclude 'node_modules' \
+  --exclude '__pycache__' \
+  --exclude '*.pyc' \
+  --progress \
+  ./ \
+  besuadmin@20.160.58.99:~/smom-dbis-138/
+```
+
+### Step 3: Deploy from Proxy Host
+
+**On the proxy host (20.160.58.99):**
+
+```bash
+# Navigate to project
+cd ~/smom-dbis-138
+
+# Load environment variables
+source .env
+
+# Verify SSH key path is correct for accessing VMs
+ls -la keys/besuadmin-us-nodes_key.pem
+
+# Ensure key has correct permissions
+chmod 600 keys/besuadmin-us-nodes_key.pem
+
+# Generate Phase 2 configuration (reads Phase 1 outputs)
+cd terraform/phases/phase1
+terraform output -json phase1_us_regions > /tmp/phase1_outputs.json
+
+cd ../phase2
+
+# Generate terraform.tfvars
+../../scripts/deployment/generate-phase2-tfvars.sh
+
+# Review configuration
+cat terraform.tfvars
+
+# Initialize Terraform
+terraform init -upgrade
+
+# Plan deployment
+terraform plan
+
+# Deploy to all 5 regions (parallel)
+terraform apply -auto-approve
+```
+
+### Step 4: Start Services
+
+**On the proxy host:**
+
+```bash
+cd ~/smom-dbis-138
+
+# Start all services in parallel across all regions
+./terraform/phases/phase2/scripts/start-services.sh all
+```
+
+### Step 5: Verify Deployment
+
+**On the proxy host:**
+
+```bash
+cd ~/smom-dbis-138
+
+# Check status of all regions in parallel
+./terraform/phases/phase2/scripts/status.sh all
+```
+
+## Alternative: Use Convenience Script
+
+**On the proxy host:**
+
+```bash
+cd ~/smom-dbis-138
+source .env
+./scripts/deployment/deploy-phase2-from-proxy.sh
+```
+
+## Troubleshooting
+
+### SSH Key Issues
+
+If the proxy uses a different SSH key:
+
+1. Check if you have the proxy key:
+   ```bash
+   ls -la ~/.ssh/ | grep -E "(proxy|bastion|nginx)"
+   ```
+
+2. Try connecting with different keys:
+   ```bash
+   ssh -i ~/.ssh/id_rsa besuadmin@20.160.58.99
+   ssh -i ~/.ssh/id_ed25519 besuadmin@20.160.58.99
+   ```
+
+3. Check SSH config:
+   ```bash
+   cat ~/.ssh/config | grep -A 10 "20.160.58.99"
+   ```
+
+### Verify VM Connectivity from Proxy
+
+**On the proxy host**, test SSH to VMs:
+
+```bash
+# Test each VM
+for ip in 10.1.1.4 10.2.1.4 10.3.1.4 10.4.1.4 10.5.1.4; do
+  echo "Testing $ip..."
+  ssh -i ~/smom-dbis-138/keys/besuadmin-us-nodes_key.pem \
+      -o StrictHostKeyChecking=no \
+      besuadmin@$ip "echo '✅ $ip: OK'"
+done
+```
+
+### Terraform Issues
+
+If Terraform can't connect to VMs:
+
+1. Check SSH key path in `.env`:
+   ```bash
+   grep SSH_PRIVATE_KEY_PATH .env
+   ```
+
+2. Verify key permissions:
+   ```bash
+   chmod 600 keys/besuadmin-us-nodes_key.pem
+   ```
+
+3. Test SSH manually:
+   ```bash
+   ssh -i keys/besuadmin-us-nodes_key.pem besuadmin@10.3.1.4
+   ```
+
+## Complete Deployment Command Sequence
+
+**Copy and run on proxy host:**
+
+```bash
+cd ~/smom-dbis-138
+source .env
+chmod 600 keys/besuadmin-us-nodes_key.pem
+cd terraform/phases/phase2
+terraform init -upgrade
+terraform apply -auto-approve
+cd ~/smom-dbis-138
+./terraform/phases/phase2/scripts/start-services.sh all
+./terraform/phases/phase2/scripts/status.sh all
+```
