Updated the file relocation function to use `settings.DATA_FILES_DIR` for theme folders and improved filename handling by prefixing with the file type. Adjusted logic to handle URLs consistently and ensure paths are properly resolved. This enhances maintainability and organizes theme files more effectively.
Introduce `_relocate_theme_file` to handle moving files to theme-specific directories in the storage system. This ensures better organization of uploaded files by associating them with a theme ID and file type, improving maintainability and structure.
Introduce helper functions to generate unique filenames, create date-based storage paths, and validate image content types. These utilities centralize and streamline file-related operations for consistency and reusability.
