Greptile Summary

This PR changes lifecycle form defaulting for mandatory attributes with a single allowed value. The main changes are:

• Adds special handling for linkset attributes in DisplayStimulusForm().
• Loads the current linkset, adds the only allowed object, and writes it back.
• Leaves scalar defaulting unchanged for non-linkset attributes.

Confidence Score: 3/5

These issues should be fixed before merging.

• Indirect linksets can load the allowed id from the wrong class and add the wrong link.

• The creation form still sends a scalar id through the linkset setter path.

• Both issues affect the single-allowed-value workflow this change is meant to handle.

• application/cmdbabstract.class.inc.php needs the linkset defaulting paths aligned for direct, indirect, lifecycle, and creation forms.

   Creation form still breaks

   The creation-form path still applies the old scalar defaulting logic to linkset attributes. If a mandatory linkset has exactly one allowed value during object creation, this calls Set() with the scalar id from array_keys(). DBObject::Set() treats non-null linkset values as an object-set iterator and calls UpdateFromCompleteList($value), so the creation form can fail before the user can submit it. This is the same single-allowed-linkset case handled below for lifecycle transitions, but this sibling path remains unchanged.

Indirect linksets misload objects

For an AttributeLinkedSetIndirect, GetAllowedValues_att() returns ids from the remote target class, because AttributeLinkedSet::GetValuesDef() uses LinkSetModel::GetTargetClass(). This branch then loads that id from $oAttDef->GetLinkedClass(), which is the link/intermediate class. When a lifecycle transition has exactly one allowed remote object, the form can throw because no link row has that id, or it can add an unrelated existing link row with the same numeric id. The indirect case needs to create a link object and set its remote external key instead of loading the link class by the remote id.
