chore: migrate to faststream 0.7#42

Conversation
Pure compat migration; no new 0.7 features adopted. Internal break points fixed: - pyproject.toml: pin bumped to faststream>=0.7,<0.8. - publisher/producer.py: OutboxProducer gained a `codec` attribute to satisfy ProducerProto[0.7]. The outbox owns its own encoding pipeline via _encode_payload and ignores the attribute at runtime. - testing.py: FakeOutboxProducer gained the same `codec` attribute; create_publisher_fake_subscriber converted from @staticmethod to instance method to match upstream's abstract base. - registrator.py: dropped `middlewares_=` from the SubscriberUsecase .add_call call (kwarg removed upstream in 0.7). Public surface (BREAKING): - Dropped the per-call `middlewares=` kwarg from OutboxRegistrator.subscriber, OutboxRegistrator.publisher, OutboxRoute, and the FastAPI router's subscriber/publisher overrides. Upstream removed publisher- and subscriber-level middlewares as a public surface in 0.7; install middleware at the broker scope instead via `OutboxBroker(middlewares=[...])`. Broker-scope middlewares on OutboxBroker, OutboxRouter, and the FastAPI router are unchanged. Spec: planning/specs/2026-06-03-faststream-0.7-migration-design.md.

Pure-compat migration from FastStream 0.6 to 0.7. Pin bumped to
faststream>=0.7,<0.8; no new 0.7 features adopted (broker-levelAckPolicydefault, multi-broker, MQTT, etc. each get their own follow-up spec).Internal break points fixed
