Improvement: Backend Improvements for Typing, Tests, Modularity and Pathlib

[omeryusufyagci]

Current app.py will be reorganized under backend/, with the following objectives:

• Typing: Add type hints throughout the backend
• Unit Tests: Develop unit tests for all utility and processing functions.
• Response Handling: Add a ResponseHandler class in backend/response_handler.py to handle all communication bwn BE-FE, BE-core using consistent JSON responses.
• Replace os with pathlib
• Reorganize the code under backend/:
  • Move Utils to backend/utils.py
  • Move MediaHandler to backend/media_handler.py
  • Keep app.py for route definitions and Flask app initialization.

This is a big step going towards v1.0 and offers a relatively straightforward first issue for contributors looking to make an impactful contribution to the project.
