feat: the header callsign is the station switcher; clock moves to the status bar

Switching station is the frequent act and editing a profile the rare one, but
the callsign opened the settings — so changing station took four clicks and a
scroll. It is now a dropdown of every profile: pick one and it activates. The
active one is ticked and disabled, and "Manage profiles…" stays at the bottom
for the rare case.

The list reloads on every profile change, so a profile added or renamed in the
settings appears without a restart.

The UTC clock leaves the header for the status bar, next to the database: in the
header it sat beside the frequency in the same weight and competed with it for
the eye, while being something you consult rather than watch.
