feat(ai): Integrate MCP server and threat-analyst with AI Gateway

Route AI requests through the AI Gateway for data sovereignty compliance.

Changes:
- secubox-mcp-server: ai.sh now prefers AI Gateway (port 4050), falls back to LocalAI
- secubox-threat-analyst: UCI config adds ai_gateway_url option
- threat-analyst CLI shows both Gateway and LocalAI status
- analyzer.sh and appliers.sh use ai_url (Gateway preferred)
- README updated with AI Gateway integration section

The AI Gateway ensures threat data (IPs, MACs, logs) is classified as
LOCAL_ONLY and never leaves the device, supporting ANSSI CSPN compliance.

+## AI Gateway Integration
+
+Threat Analyst routes AI requests through the AI Gateway for data sovereignty compliance:
+
+1. **Gateway (preferred)**: Handles data classification and PII sanitization before routing to providers
+2. **LocalAI (fallback)**: Direct on-device inference if gateway is unavailable
+
+The AI Gateway ensures threat data (IPs, MACs, logs) stays LOCAL_ONLY and never leaves the device.
