fix(android): address auto-save SOCKS5 validation, cursor crash, HTTP status checks and dead conditional

- Add SOCKS5 auth validation guard to auto-save LaunchedEffect in SettingsScreen.kt to prevent persisting profiles with only one of socks_user/socks_pass set (regression from removal of Save button).
- Guard getFileNameFromUri in ProfilesScreen.kt with nameIndex >= 0 to prevent CursorIndexOutOfBoundsException when content provider doesn't expose DISPLAY_NAME.
- Check connection.responseCode before reading inputStream in ProfilesViewModel.updateRemoteProfile and importProfileFromUrl, surfacing HTTP errors via errorStream instead of generic IOException.
- Replace dead conditional (selectedProfile.remoteUrl != null was always true after early return) with remoteProfile.name.isNotBlank() in updateRemoteProfile to preserve local name when remote returns blank name.
