fix(models): expose custom node models in canonical prefix mode (#11832) (#11918)

Custom provider-node models (synced, custom, and alias-backed) now appear under their configured prefix in the unified catalog when the operator's model-id prefix mode is canonical, instead of being dropped whenever alias-inclusion was otherwise disabled. Closes #11832. Thanks!
