fix: remove broken load paths from JSON-only components

- Remove load.path from JSONLambdaDesigner (TSX file deleted)
- Remove load.path from JSONModelDesigner (TSX file deleted)
- Remove load.path from StyleDesigner (TSX file deleted)

These components are now JSON-only and don't need load path references.
