Map names now come from LIST_ZONE.STB (row index = map id, matching
CWorldServer::LoadZoneData). New NPCs tab lists all placed NPCs from
list_npcs with coordinates; new Monsters tab lists all 1,193 named montypes
from LIST_NPC.STB. Both are click-to-copy GM commands (/tele, /mon) for
quick GM navigation/spawning.
Adds an nginx:alpine service serving webtools/ (item/map lookup
frontend) on port 80 alongside the existing login/char/world stack.
