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
