WIP: alternative user status design

[ShGKme]

☑️ Resolves

• The problem: too many clicks to just go to DnD, for example, to disable notifications. Opening a menu, opening a dialog box, working in it
• The proposal: separate online status and the custom status
• This is also a common practice for other messengers

I prefer the look of the collapsable, but would think it could be handy to still have the status in the modal, especially together with the revert option of previous status.
