Implement the UI part of Profile/Settings/Showcase:
- Communities/Accounts/Collectibles/Assets tabs
- drag and drop of items between "hidden" and "in showcase" sections
- ability to set individual items' visibility
- persistency (showcase saved across restarts), not exposed yet due to
missing backend API
Closes#9936
TLDR;
- all links visible in settings/popup
- persistent order of items
- drag'n'drop to reorder
- editing/deleting in a new popup
- several links of the same type
Needs changes in nimqml (to expose QAIM::begin/endMoveRows), in
DOtherSide (to expose those to NIM), in status-go (to preserve the links
order and fully save them to DB)
Fixes#9777
... to help align with original design intent
- dropped date breaks before msg groups
- show full date/timestamp in the msg header
- floating "Unpin" button on mouse hover
- no padding/spacing between messages
- some smaller code cleanups and dead code removals
Fixes#9396
- rework the way social links are displayed/editted; we now only allow to
enter a so called "handle" and then substitute that in the final URL
template
- move the "icon" model role to NIM backend
This has several advantages:
- we display only the "handle" and don't have to elide some long URL
- we won't let users enter random URLs into their profile and spoof the
viewing part into clicking it
Additionally, make the social link "button" clickable -> navigate to the
target URL, and make the tooltip behave as "usual" (on mouse hover).
