refactor(axum-rest-api-server): remove re-exports, import protocol DTOs directly

Remove pub-use re-exports from axum-rest-api-server's peer.rs and
torrent.rs that forwarded to torrust-tracker-rest-api-protocol.
All callers now import directly from the protocol crate.

Updated files:
- packages/axum-rest-api-server/tests/ (asserts, contract test)
- src/console/ci/qbittorrent_e2e/ (verify_tracker_swarm, tracker client)
- packages/axum-rest-api-server/src/v1/context/torrent/resources/ (tests)

Also adds torrust-tracker-rest-api-protocol as a direct dependency of
the root torrust-tracker crate.

Part of EPIC #1669
