Pull Request: Refactor backend URL to use a centralized configuration

Description

This pull request addresses the issue of hardcoded backend URLs in the application. The current implementation uses localhost:3000 in multiple places, making it cumbersome to update if the backend URL changes. This update introduces a centralized configuration file to store the backend URL, ensuring that changes can be made in one location and will reflect throughout the application.

Changes Made

• Created a configuration file (config.js or .env) to store the backend URL.
• Updated all instances of the hardcoded URL in the codebase to reference the new configuration file.

Updated Files and Line Numbers

• Dashboard.html - line 137
• fac_login.html - line 79
• faculty.html - line 200
• form_filling.html - line 158
• login.html - line 80

• approval.js - line 119
• stk_signup.html - line 76
• stk_login.html - line 89
• stk_dashboard.html - line 255

Benefits

• Improved Maintainability: Changes to the backend URL can be made in one place, reducing the risk of errors and ensuring consistency.
• Flexibility: The application can be easily adapted to different environments (e.g., development, staging, production) without extensive code changes.
