perf(proxy): capture/scrape browser'larında bant genişliği israfını kes

DataImpulse residential kotası hızlı tükeniyordu (15 günde 58.5 GB). CSV
analizi capture/scrape tarayıcılarının tam sayfa (resim/font/CSS/reklam/
CDN) yüklediğini gösterdi.

- pcat + emex capture: resource-blocking'e stylesheet + üçüncü-parti çöp
  (yastatic, google fonts/autofill, adsco.re, displayvertising, tidio,
  ipify) eklendi. Widget runtime CDN'leri (jsdelivr/unpkg) bilinçli hariç.
- emex: engelleme context seviyesine alındı → tüm tab'ları kapsıyor.
- pcat: ipify exit-IP probe artık PCAT_EXIT_IP_PROBE ile default-off
  (15 günde ~54k faturalı istek + 352 MB, sadece telemetri içindi).

Not: emex scraping resmi tarayıcıda yüklemiyor; URL'yi HTML'den parse edip
boyutu ayrı Range GET ile alıyor → resim engellemek scraping'i etkilemez.
