test(sveta): Write e2e tests for the iOS app badges

Outcome: done
Changed: tests/e2e/iosapp.py:1-94 (new file)
Verified by: python -m pytest tests/e2e/iosapp.py -q -> 5 passed (3 consecutive clean runs, incl. verify()); full make test -> 3348 passed, 1 skipped, 11 failed (9 tests/api/projects/workspace.py FileNotFoundError 'docker' = missing docker binary in container, pre-existing per sibling run; 1 tests/e2e/game/farm.py steal flake, passes standalone; 1 was this file's pre-fix settings-propagation race, fixed)
Findings: tests/e2e/iosapp.py locks the badge behaviour: footer badge visible on landing (.landing-footer) and /feed (.site-footer), guest topnav badge next to Login/Sign Up, mobile-panel badge after opening the hamburger, every href equals the configured ios_app_url with target=_blank rel=noopener noreferrer, and all badges disappear when ios_app_url is cleared (restored in try/finally).
Settings-flip e2e tests must sleep CACHE_VERSION_PROPAGATION_SECONDS (1.5s) after set_setting before navigating: the server caches the cache_state version for 1s (core.py:56), and the first iosapp run hit that race (badge absent on a stale render).
On a fresh DB the operational_defaults block incl. ios_app_url is never seeded because it is gated on the pre-init db.tables snapshot (schema.py:34 vs :1705), so the badge renders only after an admin sets ios_app_url.
Open: re-run make test on a docker-capable host to clear the 9 workspace.py environment failures; decide the fresh-DB ios_app_url seeding gap (PM/implementation node); farm s
