feat(ios-qa): adaptive XCUITest runner that reaches nested controls and verifies taps

JSON-driven XCUITest runner plus SwiftUI/UIKit fixture apps that drive a
real app by bundle id. The runner resolves the actual switch inside a
SwiftUI Toggle wrapper, and when a center tap misses the full-width row it
retries on the control's trailing edge via an element-anchored normalized
offset (adaptive, not a raw screen coordinate), then verifies the switch
value actually changed. A tap that silently does nothing is now reported
as an interaction failure, not a false product defect. Validated on the
simulator and on a physical iPhone.
