port 2D step 2: 40250 item_proto/mob_proto through CLZO and pack://locale/<lang>/

proto.cpp reads the 40250 MIPX/MMPT tables with the ported CLZO/TEA (156-byte
TItemTable, 255-byte SMobTable), replacing the m2dev XChaCha20 236/335 reader.
Names follow CItemData::GetName / GetMonsterName (szLocaleName, cp1252).
GDScript callers load AssetRoot.locale_file() = pack://locale/en/<name>, which
makes the EterPack chain runtime-reachable; port-map entries for the functions
a coverage run hit move to PORTED/ADAPTED.
