Fix BGP Peer Map blank node graph: numeric edge mainstat

Browse Source 
The node graph rendered empty because the edges target returned a
string mainstat ('iBGP'/'eBGP'). Grafana's nodeGraph treats edge
mainStat as numeric for layout/labelling; a string value silently
breaks the layout so no nodes are drawn (the working LS map and the
original ls_topo both cast edge mainstat to an integer).

Edge mainstat is now COUNT(DISTINCT feed)::int (BMP peer-feed count
for the router pair); the iBGP/eBGP label moves to secondarystat and
detail__session_type, which accept strings.
