feat: add gossip/NPC dialog API for quest and vendor addons

Browse source 
GetNumGossipOptions() returns option count for current NPC dialog.
GetGossipOptions() returns pairs of (text, type) for each option
where type is "gossip", "vendor", "taxi", "trainer", etc.
SelectGossipOption(index) selects a dialog option.
GetNumGossipAvailableQuests() / GetNumGossipActiveQuests() return
quest counts in the gossip dialog.
CloseGossip() closes the NPC dialog.

Uses existing GossipMessageData from SMSG_GOSSIP_MESSAGE handler.
Enables gossip addons and quest helper dialog interaction.
