Describe your changes

Enhancements to Netbird Interface Firewall Management

In Windows and Linux systems, there have been scenarios where firewall restrictions hinder the traffic on the Netbird network interface. This PR addresses the issue by enhancing how we manage firewall rules for the Netbird interface.

Changes

Introduced the AllowNetbird method across all Netbird firewall managers. This method is invoked by the ACL manager during initialization, ensuring traffic flow through the Netbird network interface.
For Linux, a default rule has been established in the "INPUT" chain of the "filter" table, allowing all incoming traffic from the Netbird network interface in booth firewall managers iptables and nftables.
For Windows, this PR does not include implementation.
