UI: FIX #2256 Hacknet server's upgrade tooltip were not handling RAM usage correctly.

Fix #2256 by using the correct formula to calculate the hashrate increase.

Slightly revamp tooltip to display both theoric and effective increase.
Add a discreet tooltip to the Production line which display details about hashrate and ram usage.

Tested by running two script by intermittence on a loop on the hacknet server.
Value displayed stay coherent all along.
