- Introduced a new upload endpoint for direct texture file uploads, allowing users to upload textures with validation for size and format. - Updated existing texture-related API responses to a standardized format, improving consistency across the application. - Refactored texture service methods to handle file uploads and reuse existing texture URLs based on hash checks. - Cleaned up Dockerfile and other files by removing unnecessary whitespace.
