Add sender_did to chat messages and new chat tables

Introduces a migration to add a sender_did column to the chat_messages table and creates new tables for chat_device_bundles, chat_inbox, and chat_one_time_keys. Updates related API routes and adds a script for sender DID migration. These changes support device-based messaging and improved chat security.
