fix(bandmap): follow the cluster's filters

The band map received the raw spot stream filtered by band alone, so none of
the cluster's filters reached it: switching on "LoTW users only" changed the
list and left the panadapter showing everyone. The same was true of hide
worked, the spotter continent, and the status and mode chips.

The predicate is extracted and shared rather than copied — two views of one
spot stream disagreeing about the same spot is the fault lib/spotDisplay
already exists to prevent, and a second copy would have drifted the first time
a filter was added.

The BAND filter is deliberately excluded from the shared part: a band map's
band is its filter, and applying the cluster's would empty every map but one.
