chore: bump app version and update Android/iOS build tooling

- Bump version to 2026.0613.2+57
- Gradle wrapper 8.12 -> 8.14; Flutter migrator flags (builtInKotlin/newDsl)
  and relax kotlin.jvm.target.validation to warning for third-party plugins
- Refresh iOS Xcode project, scheme, Info.plist, Podfile.lock and SwiftPM
  Package.resolved
