test: Improve database cleanup in JVM UI tests

- Update `AbstractNavigationTest` and `DesktopUiTests` to properly delete SQLite auxiliary files (`-wal`, `-shm`, and `-journal`) alongside the main database file during test setup.
- Refactor the deletion logic in `AbstractNavigationTest` to use a more idiomatic Kotlin sequence for file operations.
