fix(nym-api): allow simulation mode to run when another API is advancing epoch

In simulation mode, the nym-api should be able to run performance simulations regardless of which instance is handling epoch advancement, since simulations don't perform any blockchain transactions. This fix: - Allows simulation mode to proceed when another API is advancing the epoch - Skips epoch transition attempts in simulation mode - Skips actual reward distribution blockchain operations in simulation mode
