[management] Add backward compatibility for older clients without firewall rules port range support (#4003)

Adds backward compatibility for clients with versions prior to v0.48.0 that do not support port range firewall rules.

- Skips generation of firewall rules with multi-port ranges for older clients
- Preserves support for single-port ranges by treating them as individual port rules, ensuring compatibility with older clients
