Vanilla/Turtle WoW compatibility: fix UPDATE_OBJECT, chat, equipment, creatures

- Route SMSG_UPDATE_OBJECT through polymorphic parsers for correct
  vanilla format (uint8 updateFlags, 6 speeds vs WotLK uint16/9)
- Fix SMSG_DESTROY_OBJECT for vanilla (8 bytes, no isDeath field)
- Add MSG_MOVE_* handlers for other player movement relay
- Add ClassicPacketParsers::parseMessageChat with targetGuid read
  and monster-type name handling
- Resolve chat sender names from player name cache before display
- Fix CSV DBC field 0 always treated as numeric ID (fixes 16+ garbled
  Turtle CSVs including Map, AreaTable, Spell, CreatureDisplayInfo)
- Add CSV DBC validation: reject garbled CSVs (>80% zero IDs) and
  fall back to binary DBC files
- Fix ItemDisplayInfo texture component field index (14+ not 15+)
  for binary DBC with gender-aware suffix resolution
- Spawn other players as visible M2 models via creature callback
- Map name cache dedup prevents overwrites from duplicate CSV records
