[revu-bot]

This PR improves authorization controls by adding role-based restrictions to document operations and refactoring decision-making permissions. The changes include proper role decorators for structure document endpoints and a new centralized permission system for user decisions. The code is well-structured with comprehensive test coverage, though there are some minor issues with error handling and code organization.
