feat: add trade API (AcceptTrade, CancelTrade, InitiateTrade)

Browse source 
AcceptTrade() locks in the trade offer via CMSG_ACCEPT_TRADE.
CancelTrade() cancels an open trade via CMSG_CANCEL_TRADE.
InitiateTrade(unit) starts a trade with a target player.

Uses existing GameHandler trade functions and TradeStatus tracking.
Enables trade addons and macro-based trade acceptance.
