fix(type-tests): update fixtures for new additionalProperties semantics

- Update imports to use WithAdditionalProperties instead of separate types
- Simplify ObjectValue helper to properly handle additionalProperties: false
- Remove unnecessary @ts-expect-error comments for forced type errors
- Add type access tests demonstrating bracket and dot notation behavior
