[bugfix] Apply cyclic TCs when in nodestime When using `nodestime`, master does not correctly apply cyclic time controls like 40/10. This patch fixes that. Details of how game managers deal with these time controls can be found [here](https://github.com/Disservin/fastchess/blob/ccb85325b1db322658687b8be8cfe9f54c495840/app/src/game/timecontrol/timecontrol.cpp). closes https://github.com/official-stockfish/Stockfish/pull/7119 No functional change
