Fix firewall rules not loading on reboot

- Enable and start nftables service during installation
- Create /etc/nftables.conf that includes /etc/nftables.d/wireguard.conf
- nftables service now loads firewall rules automatically on boot
- Update documentation to reflect proper configuration file paths
- Remove historical VALIDATION.md document
- Clean up documentation references to non-existent scripts

 ## Usage
 
 ### Dynamic client loading
-WireGuard automatically loads clients from `/etc/wireguard/peer.d/`:
-- Add/remove client configs in `/etc/wireguard/peer.d/*.conf`
-- Run `sudo /usr/local/sbin/wg-load-clients` to reload
+WireGuard automatically loads clients from `/etc/wireguard/conf.d/`:
+- Add/remove client configs in `/etc/wireguard/conf.d/client-*.conf`
+- Run `sudo ~/wireguard.sh load-clients` to reload
 - Changes are applied immediately without restarting
 
 ### Add a new client
 ```bash
-sudo /usr/local/sbin/wg-client-manager add myphone
+sudo ~/wireguard.sh add myphone
 ```
 This creates:
-- Server config in `/etc/wireguard/peer.d/myphone.conf`
+- Server config in `/etc/wireguard/conf.d/client-myphone.conf`
 - Client config in `/etc/wireguard/clients/myphone.conf`
 - QR code in `/etc/wireguard/clients/myphone.qr`
 
 ### List all clients
 ```bash
-sudo /usr/local/sbin/wg-client-manager list
+sudo ~/wireguard.sh list
 ```
 
 ### Show client config
 ```bash
-sudo /usr/local/sbin/wg-client-manager show myphone
+sudo ~/wireguard.sh show myphone

 ### Show QR code
 ```bash
-sudo /usr/local/sbin/wg-client-manager qr myphone

 ### Remove a client
