feat(auth): add web captcha handling

- replace manual captcha screen with WebView-based VK captcha flow
- handle captcha error 14 by showing the captcha overlay and retrying with success_token
- pass captcha redirect/result state through AppSettings
- remove old captcha ViewModel, navigation, validation, and DI
- add ACRA crash reporting
- add WIP message edit mode UI/state
- update Gradle wrapper, SDK config, and dependencies
