Enhanced Memory Banks costs no power to use

[WormGrill]

Describe the bug

The Enhanced Memory Banks CBM costs no power to activate nor upkeep. In the bionics menu it also shows that it won't drain any power.

Steps To Reproduce

1. Create a character with the Bionic Game Master class, which starts with the Enhanced Memory Banks CBM
2. Turn on the CBM
3. Observe that no power is drained to activate it nor to keep it active.

Expected behavior

Unless the Enhanced Memory Banks CBM was changed recently to not cost any bionics power, it should be draining power. Or if it's intentional for it to be free, then it should be a passive CBM because there's no downside to having it active if it doesn't cost power.

Enhanced Memory Banks is currently configured to use 2 Joules per second. Bionic power is usually measured in kJ, which means it should decrease by 1 every ~9 minutes.

Is this just a display issue?
I just went to sleep with Climate Control and Dielectric Capacitance ON and woke up with same amount of bionic power as before sleep. No power sources were active, power wasn't at max and it stayed the same after ~8 hours of sleep.

[Fris0uman]

Dielectric Capacitance should (If my math is correct) use 144kJ over 8h, and Climate Control should have used 2800kJ. So there might be something fishy with climate control at least, unless it doesn't draw power when the temperature is already good.

Now that the UI will display stuff properly, this can be tested again, just to be sure.

There is in fact a problem with bionic not drawing power, this issue can be reopen.

                // Try to recharge our bionic if it is made for it
                int cost = 0;
                bool recharged = attempt_recharge( *this, bio, cost, discharge_factor, discharge_rate );
                if( !recharged ) {
                    // No power to recharge, so deactivate
                    bio.powered = false;
                    add_msg_if_player( m_neutral, _( "Your %s powers down." ), bio.info().name );
                    // This purposely bypasses the deactivation cost
                    deactivate_bionic( b, true );
                    return;
                }
                add_msg( "cost: " + to_string( cost ) );
                if( cost ) {
                    mod_power_level( units::from_kilojoule( -cost ) );
                }
