Users model has to be sorted by online status first, otherwise
`UserListPanel` sections will be duplicated. That's because:
> Note: Adding sections to a ListView does not automatically re-order
the list items by the section criteria. If the model is not ordered by
section, then it is possible that the sections created will not be
unique; each boundary between differing sections will result in a
section header being created even if that section exists elsewhere.
fixes: #6563
This is first iteration. Models have been restructured and qml adapted
to the changes.
What is left to be done:
- populate new models with appropriate data (some fields were left
default)
- use new fields in qml, use StatusMemberItem where possible
- fix all #FIXMEs introduced by this commit
iterates: #5951
- `chatType` added to `Constants` to group chat type related values
- `messageContentType` added to `Constants` to group message content type related
values
- `MessageStore` maintained per message list now
- added new `ChatContentView` component used to display chat/channel content
- components updated to display messages from the new backend
- `StatusChatToolBar` appropriately updated
- mute/unmute feature added to chat/channel list as well as to `StatusChatToolBar`
This replaces the self-built components for the user list with StatusQ's
list item component and also addresses some of the quirks that existed in the UI
related to that original component.
The user list is now responsive and properly aligned.
**This depends on StatusQ v0.18.0**
