Implement firebase authwith continue with google option and user profile page

[Prateekiiitg56]

Description
This is a major feature update that introduces a complete user authentication system powered by Firebase and adds a comprehensive, multi-functional User Profile Page.

These changes move the project from a static demo to a dynamic web application with secure user management, consistent navigation, and personalized user settings.

Key Changes
Firebase Authentication Integration

Dual Login Methods: The login.html page now supports both traditional Email/Password login and a one-click Sign in with Google option.

User Registration: A new register.html page allows users to create new accounts using Email and Password.

Secure & Scalable: All authentication is handled securely by Firebase, providing a reliable and scalable foundation for user management.

New User Profile Page (/Profile/profile.html)

Protected Route: The profile page is now a protected route; users who are not logged in will be redirected to the login page.

Dynamic User Info: Displays the logged-in user's information, including an initials-based avatar, display name, and email.

Edit Profile: Users can now update their display name directly from the profile page.

Account Management: A "Danger Zone" has been added, allowing users to permanently delete their own account after a confirmation prompt.

Sitewide UI & Navigation Consistency

Unified Navbar: The modern, responsive navigation bar has been added to all pages (Shipments, Vehicles, Routes, Schedule, Profile, etc.) for a consistent user experience.

Corrected Links: All navigation links have been updated to be root-relative (e.g., /main.html), fixing all 404 pathing errors.

Updated Branding: All footers have been updated from "Transport Co." to "MooVit" for brand consistency.

⚠️ Important Setup Instructions
To run this code, the reviewer or any future developer must add their own Firebase project configuration. The application will not be able to connect to Firebase and will be stuck on the loading screen without it.

You need to add your firebaseConfig object to the following files:

login.html

register.html

Profile/profile.js

Replace this placeholder block in each file with your own configuration:

JavaScript

const firebaseConfig = {
apiKey: "YOUR_API_KEY",
authDomain: "YOUR_AUTH_DOMAIN",
projectId: "YOUR_PROJECT_ID",
storageBucket: "YOUR_STORAGE_BUCKET",
messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
appId: "YOUR_APP_ID"
};
