fix: show pvp disguise gear on the player's own character

- MsgItem.CreateEquipmentMode reflects an active PvP disguise: armor and weapon slots carry the disguise body and weapon UIDs, and helmet, garment, weapon accessory, and wing slots are cleared

- Disguise.Show sends EquipmentMode so the owner's model redraws the disguise on event entry and every respawn, not just the status window

- Disguise.Delete sends EquipmentMode after the disguise is cleared so leaving the event redraws the real gear

- Cover disguised and restored EquipmentMode slot UIDs in TitleAndNationalityPacketTests
