Add Missing Dynamic DNS Client Settings in OPNsense Role

[fnateghi]

Issue Description

The OPNsense role currently lacks the necessary configuration for the Dynamic DNS client (os-ddclient). Additionally, the mainstream tasks for managing DDNS configurations (edit, delete, and save) need updates to handle these configurations properly.

Proposed Configuration

Dynamic DNS Configuration The following XML configuration needs to be added for the os-ddclient plugin. This will ensure the plugin can be configured and used effectively.
