wysylanie U_A, U_B, U_C do MQTT w formacie JSON podobnie jak dla innych pomiarów (np. Hz)
wysylanie U_A, U_B, U_C do InfluxDB w batchu razem z innymi pomiarami (nie osobno)
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.
