11d650060a feerate: For GetFeePerK() return nSatoshisPerK instead of round trip through GetFee (Andrew Chow)
Pull request description:
Returning the sats/kvb does not need to round trip through GetFee(1000) since the feerate is already stored as sats/kvb.
Fixes #27913, although this does bring up a larger question of how we should handle such large feerates in fuzzing.
