fix(android): Add Robolectric SDK config for tests

Added @Config(sdk = [28]) annotation to DailyNotificationRecoveryTests to fix Robolectric initialization error (targetSdkVersion=35 > maxSdkVersion=34).

All 3 combined edge case tests now pass:
- test_combined_dst_boundary_duplicate_delivery_cold_start ✅
- test_combined_rollover_duplicate_delivery_cold_start ✅
- test_combined_schema_version_cold_start_recovery ✅
