feat(GRO-106): inbound Telnyx webhook + persistence

- Add POST /api/webhooks/telnyx/messaging route with HMAC signature verification - Add services/messaging/inbound.ts: findOrCreateConversation, upsertMessage (idempotent on providerMessageId), delivery receipt handling - Register telnyxWebhooksRouter in index.ts (before auth middleware) - Add unit tests for signature validation, find-or-create, idempotent insert, delivery receipt Co-Authored-By: Paperclip <noreply@paperclip.ing>
