GET /api/messaging/platforms returns a JSON object with a platforms
array inside, but the app expected a bare array. Wraps the response
in a new MessagingPlatformResponse model.
- Adds MessagingPlatformResponse.kt wrapper model
- Updates HermesApiService.kt return type + adds profile query param
- Updates ChannelsViewModel.kt to unwrap .platforms
- Updates E2eIntegrationTest.kt mock to match new response shape
