BUG: User Profile Data Incorrect After Signup & Missing Editable Profile Page

### Is there an existing issue for this?

- [x] I have searched the existing issues

### What happened?

## 📌 Issue Overview

When a user signs up using their email, the profile information (such as name and other basic details) is incorrect, missing, or not properly populated. Additionally, there is no dedicated **editable profile page** where users can manage their personal information.

A proper profile management system is needed where users can update their details **except for their email**, which should remain non-editable.

## 🔍 Steps to Reproduce

1. Go to the Devr.AI signup page
2. Sign up using an email address
3. Complete the onboarding or login process
4. Navigate to the user profile section (if available)
5. Observe the displayed user information

---

## 🎯 Expected Behavior

- User profile should correctly display basic information (e.g., name, avatar, etc.) after signup
- A dedicated **Profile Page** should be available
- Users should be able to **edit their profile details** such as:
- Name
- Bio
- Profile picture
- The **email field should be visible but non-editable**

---

## 🚨 Actual Behavior

- User name or other basic information is incorrect, missing, or not synced properly after signup
- No proper profile page exists to manage or update user information
- Users cannot edit or correct their personal details
