perf: viewport 1366x768 + flag-uri de reducere overhead in Session 0

Pe prod scraper-ul ruleaza ca serviciu in Session 0 (fara GPU): Chromium
randeaza software. Reducerea viewport-ului de la 1920x1080 la 1366x768
inseamna ~50% mai putini pixeli de rasterizat. 1366 e sigur peste pragul
de ~1100px sub care BT scoate splash-ul "redirect to store".

Adaugate flag-uri care taie overhead inutil fara GPU: --disable-gpu,
--disable-dev-shm-usage, --disable-extensions, --disable-background-networking,
--disable-renderer-backgrounding, --disable-features=Translate.

Verificat e2e pe site-ul BT live la 1366px (formular login real, fara
splash) si printr-o rulare completa prin bot: 5 conturi, 5 CSV-uri.
