refactor: rename temp-chunks to temp-uploads and update related configurations

- Changed references from 'temp-chunks' to 'temp-uploads' across .dockerignore, Dockerfile, and various configuration files for consistency.
- Introduced a new directories configuration file to manage directory paths more effectively.
- Updated file handling in the server code to utilize streaming for uploads and downloads, improving performance and memory management.
- Enhanced cleanup processes for temporary directories to maintain a tidy file structure.
