fix: prevent infinite render loop in Codex model catalog

Break bidirectional sync cycle between catalogRows (child) and catalogModels (parent):
- Remove catalogModels from child→parent effect dependencies
- Track last sent data in ref to avoid redundant callbacks
- Sync ref when parent pushes new data to prevent false positives

Fixes severe UI jittering when adding/editing catalog entries.
