added dockerfile and dockerignore

[rishabkumar7]

This pull request introduces initial Docker support for the project, enabling containerized development and deployment. The changes add configuration files to define how the application is built and what files should be excluded from the Docker image.

Docker support and configuration:

• Added a new Dockerfile that sets up a Python 3.12 environment, installs dependencies from requirements.txt, copies the application code, and specifies the command to run the app (main.py).
• Created a .dockerignore file to exclude unnecessary files and directories from the Docker build context, such as Git metadata, CI configs, Python caches, virtual environments, and editor-specific files.
