Features: 1) Enforced password validation using Django's validate_password in password reset flows; 2) Added handling for ValidationError during password validation;

Fixes: 1) Removed redundant import for `ValidationError` from `rest_framework.exceptions`; 2) Fixed request data handling in `confirm_password_reset` to directly use incoming data instead of serialized data;

Extra: 1) Minor adjustments to error messages for consistency; 2) Cleaned up unused variables in `confirm_password_reset`.
