Make miners respect AtmosDeviceUpdateEvent.dt (#29522)

Miners' prototype have been changed to reflect this (I read
somewhere that we have about 1 atmos tick/0.5s, my tests show more
like 1/0.53 but that looks close enough).

This also means that miner's spawnAmount is now expressed in mol/s.

See: #18781
