Configuration is hardcoded instead of using environment variables

[A69SHUBHAM]

Problem

The project currently uses hardcoded configuration values (such as API URLs and settings) within the codebase.

This leads to:

• Security risks if sensitive values are exposed
• Difficulty in managing different environments (development, production)
• Reduced flexibility and maintainability

Expected Behavior

• Configuration values should be managed using environment variables
• Sensitive data should not be hardcoded in the source code
• The project should support easy setup across environments

Proposed Solution

• Move configuration values to a .env file
• Use a library like python-dotenv to load environment variables
• Add a .env.example file for reference
• Update backend code to read values from environment variables
• Update README with setup instructions

Impact

• Improves security and maintainability
• Makes the project easier to configure and deploy
• Follows industry best practices
