Notes with additional info as modal on device page

[akamarouski]

A text modal on the device page, in which various information could be written. What is the essence - for example, I want to store in such records the mail and password for the account(s) of this device, its Wi-Fi password, existing problems, and so on. So as not to store this information separately.
For the user, such information can be, for example, read-only, and can only be changed by the administrator.
