Block images via Chrome flag, not route interception; restore DataImpulse URL auth

Browse source 
context.route() (request interception) breaks URL-embedded proxy auth in
Chromium — DataImpulse proactive CONNECT auth stops working when interception
is active. Replace route handler with --blink-settings=imagesEnabled=false
Chrome flag to block images without touching the interception layer.
Restore DataImpulse URL-embedded credentials (unchanged from before IPRoyal work).
