Fix: Update Email Validation Regex for Improved Accuracy

[yxx4c]

This pull request updates the email validation regex in the authentication pages to improve accuracy and support a broader range of valid email formats. The previous regex was restrictive and did not allow for some valid email addresses. The updated regex is more permissive and adheres to standard email formatting rules.

Changes:

1. Updated Regex:

   • Old Regex: r'^[\w-.]+@([\w-]+\.)+[\w-]{2,4}$'
   • New Regex: r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'

2. Files Modified:

   • lib/features/auth/pages/forget_password_page.dart
   • lib/features/auth/pages/signin_page.dart
   • lib/features/auth/pages/signup_page.dart

Benefits:

• Improved accuracy in email validation.
• Supports a wider range of valid email formats.
• Enhances user experience by allowing more users to successfully register and sign in.

Testing:

• Ensure that the updated regex does not falsely reject valid email addresses.
• Verify that the regex correctly identifies invalid email formats.
• Test the authentication flow with various email formats to confirm the changes.
