📄 Description

Describe your changes

Support for random WireGuard ports has been added. You can now run:

netbird up --wireguard-port 0

to let the system automatically select a random available port.

This option can be helpful when running multiple devices in some NATed networks to achieve P2P connections.

Note: When upgrading from clients older than v0.25.4, the WireGuard connection port will be replaced with a randomly assigned port.
