AccountSettingsScreenTest closed its Room in-memory database in @After while the ViewModel's `settings` Flow (kept alive by stateIn/WhileSubscribed) was still querying it. That race surfaced as "connection pool has been closed" (API 29) and "attempt to re-open an already-closed object" (API 36) on the slower CI legs, while passing on 30-35/37 and locally. Leave the in-memory DB unclosed (reclaimed with the test process) so the lingering flow never hits a closed connection. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
