v1.24: Complete OPNsense/VLAN TURN configuration automation

Major improvements:

1. COMPREHENSIVE OPNsense/pfSense Guide
   - Complete network topology (LAN 192.168.1.0/24 + VLANs 20/30/40)
   - Step-by-step firewall rules for VLAN isolation
   - Detailed port forwarding tables (WAN → COTURN/Asterisk)
   - Visual flow diagrams for cross-VLAN communication
   - Testing procedures for TURN/COTURN validation
   - All rules properly ordered (Allow specific → Block general)

2. Enhanced COTURN Configuration
   - Auto-detects and binds to local IP (listening-ip/relay-ip)
   - Configured for OPNsense/VLAN environments
   - Added TLS support on port 5349
   - Proper relay port range (49152-65535)
   - Optimized for NAT traversal

3. Asterisk Auto-Configuration
   - Added ice_support=yes to all transports (UDP/TCP/TLS)
   - rtp.conf auto-configures with COTURN when enabled
   - Automatic TURN credentials injection
   - Falls back to Google STUN when COTURN not configured
   - No manual editing required

4. Baresip Auto-Configuration
   - Automatically injects TURN server configuration
   - Uses COTURN credentials when available
   - Zero manual configuration needed

AUTOMATION: All configurations now handle themselves automatically.
Nothing requires manual editing/configuration/starting by hand.

Fixes foggy instructions, replaces with crystal-clear OPNsense guide.
