Improve UI for Dashboard

## Feature Description
Improve the UI for the `/dashboard` page, which appears upon successful sign-up. This includes making the design more visually appealing and ensuring it is fully mobile-friendly.

## Problem Statement
The current `/dashboard` page lacks a polished UI and is not optimized for mobile devices. This leads to a subpar user experience, especially for users accessing the platform from smartphones or smaller screens.

## Proposed Solution
1. Redesign the `/dashboard` page with a modern and clean UI.
2. Optimize the layout and components for responsiveness to ensure a seamless mobile experience.
3. Add proper alignment, spacing, and font styles to enhance readability.
4. Incorporate visually appealing elements, such as gradients, icons, and animations, if appropriate.

## Alternative Solutions
1. Focus only on the mobile design without altering the desktop layout.
2. Create a separate mobile view of the dashboard.

## Additional Context
- **Screenshots/mockups:** Please provide the current UI images for reference.
- **Use cases:**
- Users accessing the dashboard after signing up on a desktop.
- Users navigating to the dashboard from a mobile device.
- **Performance considerations:** Ensure the changes do not impact page load time significantly.
- **Security implications:** None expected from a UI redesign.

## Implementation Suggestions
### Technical Approach
- Use **Tailwind CSS** or **ShadCN** libraries for styling.
- Employ media queries to adapt the design for mobile.
- Implement a modular structure to reuse components.

### Potential Challenges
- Ensuring pixel-perfect responsiveness across various devices and screen sizes.
- Maintaining consistency with the platform's overall design language.

### Required Dependencies
- Frameworks and libraries used in the current project (React, Next.js, etc.).
- Any UI libraries being leveraged (e.g., RadixUI, AdixUI).

## Success Criteria
- [ ] The `/dashboard` page has a modern and visually appealing design.
