When the pfSense SNMP data included an interface entry with an empty name, service discovery crashed with TypeError: 'item' must be a non empty string or ommited entirely, got '' because Service(item="") is not allowed.

Empty-name entries are now skipped during parsing so that discovery yields only valid services.
