Following the addition of support for custom profile fields in the
user info popovers, we redesign the popover to have a cleaner look.
* Switch top section design from centered to left-aligned.
* Move mute/unmute and manage user options behind a \vdots menu.
* Move the local time and status into a new block.
Almost all design changes ideas are from discussion on chat.zulip.org;
see "#design > pronouns in profile card" for details.
