Restrict the predicate to nativeFlowMessage.

InteractiveMessage also supports storefront, collection, carousel, and Bloks payloads. The current check can set device_fanout: 'false' for those non-native-flow messages. Check interactiveMessage?.nativeFlowMessage instead, and add native-flow and non-native interactive coverage.

In `@src/client/coordinators/WaMessageDispatchCoordinator.ts` at line 640, Update
the isInteractiveNativeFlow predicate in WaMessageDispatchCoordinator to check
interactiveMessage?.nativeFlowMessage rather than the broader interactiveMessage
object, preserving device_fanout behavior for native-flow messages while
excluding storefront, collection, carousel, and Bloks payloads. Add coverage for
both native-flow and non-native interactive messages.

P2: isInteractiveNativeFlow is true for every interactiveMessage (list, button, carousel), but the device_fanout=false fix is scoped in the PR description and by the <biz> companion to native-flow messages only (resolveButtonAddonKind only matches interactiveMessage.nativeFlowMessage). As written, legacy interactive messages and group interactive sends that never attach a companion also get device_fanout: 'false', which can change fanout/delivery to secondary devices outside the intended scope. Narrow the check to native-flow messages, e.g. !!unwrapMessage(messageWithIcdc).interactiveMessage?.nativeFlowMessage, so only the companion-carrying stanzas disable fanout.
