feat: new UI possible improvements

[ymarcon]

• Creating a new user as administrator through the UI: Password needs to be entered only once (used to be twice as conformation)
• The dropdown menu for groups when adding/editing a user: Would be nice to have a filter option when you start typing
• The dropdown menu for groups when adding/editing a user: Would be nice to have the groups ordered alphabetically by default (easier to search)
• Within the "Users" tab: Maybe make it possible to sort the table on specific columns, e.g, name, email, status, role, etc
• Within the "Users" tab: Would be nice to have the users table ordered alphabetically on "name" by default, instead of the order of creation
• Within the "Users" tab: When creating a user with a password of at least 8 characters (thisisatest) & click save: The field is closed with a popup "failed to save user". This is because there is no capital letter, number or special character in the password. It would be better to have the password checked before trying to save & let the user know the password is not ok whilst the window is still open. Now, when the add user field closes, an admin will have to start over without a notification of what went wrong.
• Within the "Groups" tab: Maybe make it possible to sort the table on specific columns, e.g, name, etc
• Within the "Groups" tab: Would be nice to have the groups table ordered alphabetically on "name" by default, instead of the order of creation
• It was also possible to click on a group in Agate and see which users are part of it. Now it's only possible to edit or delete a group. The same goes for users btw, where you were able to see, e.g., created date, last login, authorizations, etc.
