chore: bump version to 3.9.0-3

- tests/App.test.tsx: remove outdated SettingsPage mock, use dynamic import
- database/tests.rs: remove unused field, use struct init syntax
- deeplink/tests.rs: use idiomatic assert!() instead of assert_eq!(true)
- support.rs: add #[allow(dead_code)] for test utilities
- usage_stats.rs: code formatting
