The camera orientation controls publish whether the map is tilted and the
camera's whole-degree heading instead of writing the buttons' attributes,
and answer tilt and north-up through the globe actions store. The new
GlobeCompass renders the heading, so a rotating camera re-renders only the
compass. The store drops an unchanged camera state and keeps each clear
owner's busy state, so the buttons show the shell that answers them: a
shell replaced by a newer one, or disposed mid-clear, leaves the live
shell's state alone, and an older shell that answers again shows its own.
createOwners gains owns() and ownerOf().
The Radio panel's and Cockpit's Enable, launcher, station tag,
transport and volume controls call RadioControls through the radio
store instead of DOM listeners. A refused station tag gets the kept tag
back from act(), which now returns what the answering action returned.
The Cockpit's station steps keep rotate: false. The unused element
fields go from the shell.
SdrCard calls LocalSdrControls through radio store actions instead of
DOM listeners, and renders its gain options from the receiver's own
R820T gain steps with page-language labels. The display and radio
stores share one owner list (createOwners): the newest connected owner
with an action answers it.
