Mariusz Kogen 6ecaeb4fde fix initiall setup as user and clear messaging (#2848)
* fix initiall setup as user and clear messaging

* fix this and that :)

* add IPv6 support to validate_ip function

* Use vpn-clearnet as name for the interface

* Rebrand and finish with docs link

* set static clearnet name

* Magic clearnet to the end :D

* change the command name

* the name is magic-clearnet

* wireguard-vps-proxy-setup

* one more fix

# Wireguard VPS Proxy Setup
# =============================================================================
#
# This script automates the setup of a WireGuard VPN server on a remote VPS
# for StartOS Clearnet functionality. It handles:
#
# 1. SSH key-based authentication setup
# 2. Root access configuration (if needed)
# 3. WireGuard server installation
# 4. Configuration file generation and import
#
# Usage:
# wireguard-vps-proxy-setup [-h] [-i IP] [-u USERNAME] [-p PORT] [-k SSH_KEY]
#
# Options:
# -h Show help message
# -i VPS IP address
# -u SSH username (default: root)
# -p SSH port (default: 22)
# -k Path to custom SSH private key
#
# Example:
# wireguard-vps-proxy-setup -i 110.18.1.1 -u debian
#
# Note: This script requires root privileges and will auto-elevate if needed.
