fix: critical bugs from deep audit

- Fix copy_files() data loss: implement real copy_file across full stack (FileWritePort, FileManagementUseCase, stubs, service, repository with atomic CTE + dedup ref_count increment, batch_operations caller) - Fix plaintext password in replace_default_admin: hash password via PasswordHasherPort before User::new() - Fix CalendarService hardcoded user_id: unify CalendarUseCase trait with explicit user_id parameter on all methods, remove zombie _for_user duplicates and hardcoded 'current_user_id', update 20 CalDAV handler call sites - Previous session: migrate DedupService to PostgreSQL (storage.blobs), atomic CTEs with compensation for file/folder repository operations
