Fix "show all neighbors" rendering edges only in the PNW

Browse Source 
getAllNodeNeighbors() hard-defaulted to region='SEA' when no region was
selected, so the map only ever returned PNW (Seattle/Salish catch-all)
neighbor edges even though node dots render for all regions. Drop the
region filter entirely when no region or group is selected so edges show
for every region, still bounded by the viewport bbox, lastSeen, and node
types. The neighbor-edge MV is intra-region only, so this never produces
cross-region lines.
