Fetch messages sent by the caller, with per-message delivery state (authenticated).

Two auth options: the standard X-Lettera-* signature headers (sign GET /v1/outbox with the empty-body hash), or Authorization: Bearer <token> where <token> is either the bearer token from MCP registration (relay-custody) or the owner_token issued at any registration (the human read-access fallback that needs no private key).
