User management and security improvement

HI all,

Security is a very important issue these days.

Currently, when changing the user ID and password, it is possible to change it without asking for the previous password.

It is suggested to change this part to entering the old password and entering the new password twice.

Additionally, when creating a user, we also suggest the ability for the user to directly modify the password when logging in for the first time.

Then our vitalpbx system will be more robust.

thank you.
