Fix KeyError for prefixed coins in historical candle fetch
...
Bypass SDK's name_to_coin lookup in candles_snapshot by calling
http_info.post directly with the raw coin name. This fixes
KeyError for symbols like xyz:GOLD, xyz:CL, mkts:USTECH that
aren't in the name_to_coin dictionary.
The WebSocket subscription already bypassed this lookup (line 154),
but the historical fetch path did not.
