refactor: remove double-cast patterns from group 4 test files

- Replace all 'as unknown as Type' patterns with proper typing
- Use 'as Partial<Type> as Type' for valid mock objects
- Add null/undefined validation in Subgraph.addInput/addOutput
- Update SubgraphEdgeCases tests to expect validation errors
- Use @ts-expect-error for intentionally invalid test values in ComboWidget
