- Replace interfaces array with interface_type string and requires_port boolean
- Add database migration for schema change
- Update backend model, API schemas, and validation
- Update frontend types and tool workshop UI
- Add dropdown for interface type selection
- Conditionally show/hide port fields based on requires_port
- Update tests and mock data
- All frontend tests pass (37/37)
- Frontend typecheck and lint pass
