Added bulk material update endpoint and support for deprecation handling logic:

- **Controller**: Introduced `updateMaterial` method in `MaterialController` for batch material updates.
- **Service**: Implemented update logic in `MaterialService` to handle both updates and deprecations based on the new `MaterialUpdateDTO`.
- **Transformer**: Updated `MaterialUpdateDTOTransformer` to map deprecation status and remove unused fields.
- **Repository**: Added `updateByPartNumber` and `deleteByIds` methods in `MaterialRepository` for efficient updates and deprecations.
