feat: add iPad QA-AUTOMATION for App Store screenshots

Add screenshot capture and resize pipeline targeting iPad Air 11-inch (M3)
to address Apple's Guideline 2.3.10 rejection (non-iOS status bars). Adapted
from the iOS repo's QA-AUTOMATION pattern with iPad-specific changes: auto-boot
simulator, xcodebuild integration, and tablet-11 (1668x2388) App Store sizing.
