fix(folio): build green on Android assemble + iOS framework link

- Drop ksp/metro/navigation3 plugin aliases - not actually applied
  by any module in this PR (deferred follow-up).
- import awaitAsOne from app.cash.sqldelight.async.coroutines for
  the suspend single-row reads enabled by generateAsync = true.
- Drop kotlin.js.ExperimentalWasmJsInterop opt-in from common
  compilerOptions (it isn't valid for android/jvm targets).
- :app:shared androidMain pulls in androidx.activity:activity-compose
  for the BackHandler actual.
