feat(ups): ramura "pe baterie" se poate testa fara scoaterea din priza

Lantul de protectie are doua jumatati. Prima - "UPS-ul chiar raporteaza trecerea
pe baterie?" - e deja dovedita de perechile de evenimente Kernel-Power 105 de la
panele reale din 2026. A doua - decizie, alerta, oprirea curata a Oracle - nu
avea cum sa fie exercitata decat asteptand o pana.

Acum monitorul accepta un SIMULARE.json care suprascrie citirea de alimentare.
Doua garzi, ca un fisier uitat sa nu opreasca serverul pe date inventate:
"expira" e obligatoriu si e sters automat la depasire, iar oprirea e in gol daca
nu se cere explicit "dryRun": false. Cat e activa, fiecare ciclu scrie WARN in
log si -Mode Status o afiseaza.

test-battery.ps1 conduce simularea si urmareste logul; sterge fisierul si daca e
intrerupt. Cu -ConfirmReal 'DA-OPRESTE-SERVERUL' devine repetitie reala pentru o
fereastra de mentenanta - singurul mod de a masura cat dureaza shutdown immediate
pe baza de productie, informatie de care depinde alegerea pragurilor.

Validat in gol pe 27.08.2026: detectie la 15:36:09 + email de pana, apoi exact
trei cicluri de confirmare, declansare pe pragul de 35% la 15:36:40 si secventa
parcursa integral. Oracle a ramas Running.
