feat: expand XCUITest coverage to 54 QA scenarios with accessibility IDs and fix test failures

Add 22 new UI tests across 8 test files covering Home, Schedule, Progress,
Settings, TabNavigation, TripSaving, and TripOptions. Add accessibility
identifiers to 11 view files for test element discovery. Fix sport chip
assertion logic (all sports start selected, tap deselects), scroll container
issues on iOS 26 nested ScrollViews, toggle interaction, and delete trip flow.
Update QA coverage map from 32 to 54 automated test cases.
