refactor(architecture): eliminate internal package and complete cordis single-owner model and repository migration
- Physically purged all legacy internal/ packages, centralized pkg/model/ and pkg/repository/ - Migrated domain models and database repositories into self-contained owner plugins (user, auth, message_gateway, admin, upload, risk_control) - Decoupled cross-plugin interactions via pure core/contracts and typed EventBus - Ensured 100% test coverage pass, zero data races (-race clean), and 0 lint issues in make code-check
