fix: clean up code structure and remove unused code blocks

[Dhanushree-Microsoft]

Purpose

This pull request updates dependencies in both the backend and frontend to address compatibility, security, and feature improvements. The main changes include adding and upgrading several Python and JavaScript packages, as well as aligning version constraints for consistency across the project.

Backend dependency updates:

• Added the following dependencies to the override-dependencies list in src/backend-api/pyproject.toml: azure-core, urllib3, black, cryptography, pyjwt, and pyopenssl, all pinned to specific versions.
• Upgraded fastmcp from version 2.14.2 to 3.2.0 in src/processor/pyproject.toml to ensure compatibility with the latest features and fixes.
• Changed the version constraint for authlib in src/processor/pyproject.toml from a minimum version (>=1.6.9) to an exact version (==1.6.9) for consistency and reproducibility.

Frontend dependency updates:

• Upgraded picomatch from version 2.3.1 to 4.0.4 in src/frontend/package-lock.json and removed a redundant sub-dependency, ensuring compatibility with Node.js >=12. [1] [2]
• Added a version constraint for picomatch (>=2.3.2) to dependencies in src/frontend/package.json to ensure the correct version is used.

Does this introduce a breaking change?

• Yes
• No
