Test variant of loss prevention [Block calls if provider cost greater then client cost]

[Aminuxer]

try add LossPrevention

I fixed SQL-query for get providers costs in case then uplink prefixes don't exact match with isp prefixes

for example, tariff rates has prefix 4495 (price 2.56) but uplink prefixes has only 44 (price 2.9) - this call blocked due money loss

Global option like loss prevention if uplink cost greater client cost can be useful ?
