Fix crashes in network and software PDF exports

[angelmq152]

Description

Fixes several independent GLPI 11 export failures:

• handles network ports with no instantiation type instead of calling an invalid callback;
• exports every IP address attached to a port, avoiding TooManyResultsException on dual-stack ports;
• skips an absent installation user instead of passing null to formatUserName();
• uses getEntitiesRestrictCriteria() with the GLPI array query builder when exporting software versions.

The upstream repository has issues disabled, so there is no issue number to reference.

Validation

• git diff --check passed.
• Local PHP/GLPI tests could not be run because this environment does not provide PHP; the project CI should validate against GLPI 11.
