Adds NextDeveloper\Commons\Helpers\ObjectHelper with three methods:
- getPublicObjectName() — strips \Database\Models from a full model class name (e.g. NextDeveloper\IAAS\Database\Models\VirtualMachines → NextDeveloper\IAAS\VirtualMachines)
- getPrivateObjectName() — reverses the above (short form → full model class)
- getObject() — resolves and fetches a model by object type and ID/UUID
