User Registration Error Feedback Missing

# User Registration Error Feedback Missing

## Problem
On the user registration form, when an error occurs, there is no visible feedback mechanism such as a toast notification, inline error message, or alert. Users are left without guidance on what went wrong.

## Impact
- Users may get confused if their registration fails silently.
- Leads to poor user experience and frustration.
- Increases the likelihood of repeated failed attempts.

## Suggested Fix
- Implement toast notifications, inline error messages, or modal alerts to display validation and server-side errors.
- Ensure error messages are clear, concise, and specific .
- Maintain consistency with the app’s existing design system (colors, typography, etc.).

## Expected Outcome
- Users immediately understand why their registration failed.
- Improved usability and smoother onboarding process.
- Reduced frustration and better error recovery.
