Fix spike detection bug causing stuck values

Browse Source 
When a spike was detected in voltage, current, power, energy, or frequency,
the code sent previous values but never updated the prev_* variables.
This caused the system to get stuck reporting old values indefinitely
after any significant measurement change.

Now all prev_* variables are always updated after spike detection,
ensuring values can change again after being filtered.
