.SYNOPSIS
    Schimba pragurile de oprire din config.json fara sa atinga parola SMTP,
    si reporneste monitorul ca sa le citeasca.

.DESCRIPTION
    Se ruleaza PE SERVER, ridicat (Administrator).

    Configuratia e citita o singura data, la pornirea buclei, deci orice modificare
    cere repornirea taskului - de asta se ocupa scriptul.

    Fara parametri, doar afiseaza pragurile curente.

.EXAMPLE
    # praguri largite pentru un test de autonomie
    powershell -ExecutionPolicy Bypass -File .\set-praguri.ps1 -Minute 60 -Procent 25

.EXAMPLE
    # inapoi la valorile de productie
    powershell -ExecutionPolicy Bypass -File .\set-praguri.ps1 -Minute 10 -Procent 35
