AtomicIP#459) Add register_category_path and validate_category functions with depth validation. Update assign_ip_to_category to enforce category registration before assignment. Add comprehensive tests for hierarchy depth (5+ levels), path traversal attempts, and invalid hash validation. - Add ContractError variants: InvalidCategoryHash, InvalidCategoryDepth, CategoryNotFound - Add DataKey::CategoryDepth for depth tracking - Add CategoryInfo struct for path metadata - Add MAX_CATEGORY_DEPTH = 10 constant - Update api-reference.md with category schema documentation

Summary
Implements a hierarchical category assignment system for IP records to support deep organizational structures (e.g.,
Software/Cryptography/ZK-Proofs). Closes #459.Changes
