feat: implement HTTPS for secure website protocol

[abhisheknanaware]

Summary of changes

This pull request introduces HTTPS support to the server configuration, ensuring secure communication over the network. The following changes have been made:

• Server Configuration: Added sslCertPath and sslKeyPath to the serverConfig object in src/server/config.js to specify the paths to the SSL certificate and key files.
• Server Setup: Updated src/server/server.js to import https and fs modules and configure the server to use HTTPS by creating an HTTPS server with the specified SSL options.
• Client-side Redirection: Modified src/client/App.vue to include logic that redirects users from HTTP to HTTPS, ensuring secure access.
• Dependencies: Updated package.json to include https and express as dependencies.

Motivation

The primary motivation for this change is to enhance the security of the application by encrypting data transmitted between the client and server. This is particularly important for applications that handle sensitive information, such as login credentials.

How to verify

1. Configuration Tests: Run jest tests in tests/config.test.js to verify that the server configuration includes SSL paths and throws errors if they are missing.
2. Server Tests: Execute jest tests in tests/server.test.js to ensure the HTTPS server is set up correctly and handles missing SSL files appropriately.
3. Client Tests: Use jest to run tests/AppMounted.test.js to confirm that the client correctly redirects from HTTP to HTTPS.

Ensure that the SSL certificate and key files are correctly placed at the specified paths before starting the server.
