test(SDK-518): increase unit test coverage on core SDK surface

   - Replace placeholder root test with public surface export checks
   - Add event-handler wiring/dedup and platform URL-handler tests for Iterable.ts
   - Add bridge proxy tests for initialization and embedded messaging in IterableApi.ts
   - Add auth handler tests for string/null/undefined/timeout resolution paths
   - Raise Jest coverage thresholds for core touched files
