What was the deal with the Soviet obsession over contra-rotating coaxial propellers? Was there just one senior designer in the USSR with this obsession and a lot of influence?

I guess in this case the reason is that the Orlyonok simply used the engine of the Tu-95 bomber, this was the most powerful turboprop engine at the time (probably still is).
As for the Kamov helicopters, no idea, but apparently coaxial rotors are more efficient (e.g. better climb rate) than the traditional helicopter design. The "next generation" Sikorsky–Boeing SB-1 also uses coaxial rotors:
