Fix online mode creature spawning and packet parsing
- Fix encryption desync by tracking decrypted header bytes in world socket - Fix UPDATE_OBJECT movement block parsing to handle 3.3.5a update flags - Fix UNIT_FIELD_DISPLAYID index (67, not 71) - Add creature spawn/despawn callbacks with DBC-based model loading - Add SMSG_COMPRESSED_UPDATE_OBJECT opcode support
