Implement browser-based e2e tests covering: - Tests 1-5: Stats progression (cohort, feed, eggs, moves, backdating) - Test 6: Event viewing and deletion UI - Test 7: Harvest outcomes with yield items - Test 8: Optimistic lock selection validation Includes page objects for reusable form interactions and fresh_db fixtures for tests requiring isolated database state.
