Add S3 utility module and refactor S3 functions into it

Created a new `s3.py` utility module for handling S3 interactions including file uploads and generating presigned URLs. Refactored views to utilize these new utility functions and moved the PDF collection type function to a new `utils.py` module to improve code organization and readability.
