Messaging · People: members, a profile card, online status and a status setter

MemberList sets members online and offline by name, each group a list
under its count. A press or an arrow chooses one; Enter or a double
press acts on them; offline members go quiet. UserProfileCard shows a
person's picture with presence, name and standing, title, status, the
time in their zone, and Message and Call, each only with a handler.
OnlineStatus draws a presence's dot and word; Presence now names itself
and gives its color, in data_display, its one home.

StatusSetter holds a draft seeded from the owner's status: an emoji
from a picker field, words in its own text field, and when they clear.
Suggestions fill all three; Save hands the status over and Clear status
removes it. The emoji field reuses the date pickers' field, whose
trigger ignores the Enter release after a pick.
