fix: Add idle_cycles_burned_per_day field

[berestovskyy]

The field was missed in the canister status output.

@berestovskyy just to clarify, I believe that idle_cycles_burned_per_day value already includes the compute_allocation additions in it?

So if I update my canister to have a 1% compute allocation (from zero), the idle_cycles_burned_per_day seems to increase by 864 billion (per percentage point increase).

Is this correct?

[berestovskyy]

Yes, this field is used internally and returned in canister_status, but it's not currently visible in dfx for some reason. By increasing the compute allocation by 1%, we should see the idle_cycles_burned_per_day field increase by 10M cycles multiplied by 86,4K seconds (one day), which equals 864 billion cycles.
