VPN Status Indicator v1.12

What's Changed in v1.12

• Fixed configuration bindings (cfg_* aliases) in General settings so the check interval and other options properly load and save.
• Added a dedicated full-width Setup Guide tab in settings with concise provider configuration examples (NordVPN, WireGuard, OpenVPN, Tailscale, Mullvad, ProtonVPN, NetworkManager).
• Synced popup layout toggle behavior and popup dimensions with latest Plasma 6 standards.
