A "Compact home clock" switch under Settings > Clock swaps the World clock
tab's analog face for a row: a home glyph, the city, "Home · <zone name>"
and the time, in the seconds-aware style the city rows use and spoken to
the minute like them. It is drawn the way the automatic local clock's row
is, through one shared pinned-row composable, and the local row still sits
directly under home. Off by default.
Like show-seconds it is display-only, so it is its own preference and flow
(world_clock_compact_home) rather than a clock default, and it is applied
outside the tick so flipping it does not restart the ticker. Backups carry
it; older files restore it as off.
Closes#29.
