fix(02-07): use kotlinx.coroutines.test.runTest in commonTest for wasmJs

- Add kotlinx-coroutines-test to commonTest dependencies in composeApp
- Refactor AuthSessionTest and LoginViewModelTest from runBlocking to runTest
  so the wasmJs test target compiles (runBlocking is JVM/Native-only)
- App.kt picks up spotless-imposed brace blocks under the auth-gate when
- Log pre-existing SecureAuthStateStoreContractTest and ios SecureAuthStateStore
  ktlint failures to deferred-items.md (out of scope per gsd scope-boundary rule)

Rule 3 (blocking): adding the multiplatform test runtime is needed so
./gradlew check on commonTest sources can compile across all KMP targets.
