feat: Add password field to AuthUser schema and update user management logic

This commit introduces a new optional `password` field to the `AuthUserUpdateRequest` schema, allowing users to update their passwords. The ManageUsers component is updated to handle password input, including validation for minimum length and an option to keep the current password. Additionally, the backend logic is modified to hash and store the new password when provided. Documentation has been updated to reflect these changes.
