Design a privacy-first 2FA authenticator for Android aimed at security-conscious office workers and young adults. Users should see their time-based codes in a clean list and copy them with one tap, with carefully crafted light and dark themes. All 2FA account data stays on the device in an encrypted database. Let users create an encrypted local backup to a file they choose, restore it on a new phone, and trigger a panic wipe that instantly removes all tokens. Please use Kotlin with an MVI-style state approach and Jetpack Compose for the UI, set min SDK to 33 and target 35, and include full localization for ru-RU and hi-IN.
