... 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).
