Hi Team,
I trust this message finds you well. I'm reaching out regarding a contribution to the seatunnel-web project. Before submitting the pull request, I wanted to inquire if the team has any specific suggestions, especially since this marks my initial contribution. I will raise the PR seperately. Outlined below are the key modifications: 1. Implemented a null check during new user creation to prevent potential unknown exception. 2. Exclusively granted access to the "ADMIN_USER" for the user management section. 3. Concealed the user management section from regular users. 4. Rectified the data type of "ADMIN" user data during the database initialization process. I look forward to your feedback and guidance. Thanks Haneesh
