Add file attachment functionality for equipment management

- Introduced DTO for file attachments with metadata (objectKey, originalFileName, contentType, sizeBytes, downloadUrl).
- Updated Equipment DTO to include an optional attachment field.
- Implemented endpoints for uploading and deleting equipment attachments.
- Enhanced Equipment service to handle file storage and retrieval using S3.
- Updated EquipmentEdit, EquipmentList, and EquipmentShow components to support file attachment input and display.
- Configured S3 settings in docker-compose and environment files.
