feat(07-03): layout.spec.ts — UI-SPEC Rules 1-4 + harness self-validation
- Rule 1: boundingBox assertions for BottomTabBar Calendar/Lists tabs (≥44px),
PhoneNav settings button (≥44px), New Event FAB (≥56px) on both profiles
- Rule 2: scrollWidth ≤ clientWidth on /calendar and /lists
- Rule 3: BottomTabBar in-viewport (bottom edge ≤ viewport height), PhoneNav visible
- Rule 4: navigation landmark locatable by role+name (getByRole with accessible name)
- Self-validation: addStyleTag injection proves Rule 1 tracks geometry (20px height <44),
proves Rule 2 detects overflow (2000px body width); both recover after removal
- Runs on iphone (WebKit/390px) and pixel (Chromium/412px) profiles; 30 tests pass
