[Bug]: `ACLExtendedRule` allows out‑of‑range port numbers (0 or >65535) in `source_ports` / `destination_ports`

[pheus]

NetBox access-list plugin version

v1.9.1

NetBox version

v4.4.1

Steps to Reproduce

1. Create an Extended ACL and add a new Extended Rule.
2. Set Protocol to TCP or UDP.
3. In Source Ports or Destination Ports, enter one of: 0, 65536, 70000.
4. Save the rule (UI or API).

Expected Behavior

Reject any integer not in 1 - 65535 (inclusive) when the protocol is TCP/UDP.

Observed Behavior

The rule saves successfully with 0 and values >65535.

Impact

Invalid values can propagate to generated configurations and cause deployment errors.
