Pick location on map gathered its surrounding nodes before opening, and that
meant reading the contact list from the radio whenever the session hadn't
cached it. A companion refusing that read (ERR_CODE_BAD_STATE, which the log
shows all session) held the picker closed through every retry, twenty-odd
seconds, only to open with no contacts anyway. Our own position waited the
same way after Device config dropped its cached self-info.
The picker now opens on what is already in hand: cached contacts and
self-info (DeviceState.peek_contacts / peek_self_info) and our own history,
via gather_markers(wait=False). Whatever the cache lacked is fetched behind
the open map and joins it through MapScreen.set_markers when the radio
answers. The read is never cancelled, so a fetch another screen shares
survives the picker closing. The Map tool and the node page keep waiting,
unchanged.
