Refactor API imports and restructure services

- Updated import paths for `upsertProductOrEventApi`, `deleteEventDataApi`, `deleteProductApi`, `getProductApi`, `getAllProductsApi`, and `renameProductApi` to point to the new `products` directory.
- Removed old API files for `UpsertProductOrEventApi`, `deleteEventDataApi`, `deleteProductApi`, `getProductApi`, `getAllProductsApi`, and `renameProductApi`.
- Introduced new implementations for the above APIs in the `products` directory.
- Added `MaterialCollisionDetector` component to handle material collision detection using a web worker.
- Updated various components to utilize the new API structure and ensure proper functionality.
