fix(1.0.7): disable Trusted Types engine-wide via Blink feature flag

The 1.0.6 fix (strip require-trusted-types-for from CSP via
onHeadersReceived) didn't take effect: cliqz/adblocker calls
session.webRequest.onHeadersReceived during enableBlockingInSession,
overwriting our hook (Electron permits only one listener per session).

Replace with engine-level kill switch:
  app.commandLine.appendSwitch('disable-blink-features', 'TrustedDOMTypes')

Makes the entire Trusted Types runtime feature inert, so
require-trusted-types-for CSP becomes a no-op site-wide. Safe in this
kiosk/single-user context; only relaxes one security boundary that
sites use to harden against XSS via adblocker-style script injection —
which is exactly what we need to neutralize for cliqz's anti-anti-adblock
scriptlets on YouTube.
