概要

IDのnewtypeパターン使用と、それに伴うsession周りのインターフェースの変更

domain/modelとbackend_app/extractorの変更をアプリケーション全体に反映しました

Pull request overview

This PR introduces newtyped identifiers (e.g., ProblemId, UserDisplayId, SubmissionId, etc.) and refactors session handling to pass a parsed SessionUser through the application (via a new Axum extractor), propagating these interface changes across domain, infra, usecase, and backend_app layers.

Changes:

• Introduce/propagate ID newtypes across domain models, repositories, infra adapters, and usecase DTOs/services.
• Replace “session_id string lookup” patterns with SessionUser (and add ExtractedSessionUser for handlers).
• Update backend_app request/response conversions and tests to match the new types.

lib/backend_usecase/src/service/editorial.rs:19

• After switching the service APIs to accept session_user: Option<SessionUser>, EditorialService no longer reads from the injected session_repository anywhere. Consider removing the SessionRepository generic/field (and updating new + DI) to avoid dead/unused wiring and potential dead_code warnings.
