Fix registration error handling to reflect internal errors in the UI

[AashifAmeer]

After a user successfully registers, if any internal error occurs (e.g., during email sending or other post-registration processes), the error is not properly reflected in the UI The UI shows an empty box. This prevents users from understanding the issue and taking appropriate action.

Before:

After fixing the issue:

Fixes #89

@AashifAmeer
I have reviewed and implemented the necessary changes to handle internal errors during registration.

Changes Implemented:

1.Added error handling: Wrapped critical registration functions with try-catch blocks.
2.Improved UI feedback: Now, users receive error messages if something goes wrong during registration.
3.Logged errors for debugging: Internal errors are logged to help with troubleshooting.

Could you please review my approach and let me know if any improvements are needed? Thanks!

Hi @Hardik301002 I have already fixed the issue. No need to work on this

@AashifAmeer thanks for this commit. "Internal Server Error" really doesn't convey the message to the front end user though. Can you check if it's 500 and then display a message such as "System error. Contact the administrator." Also, can you fix the same issue on the login screen?
