feat(editor): SQL spawn export for AzerothCore/TrinityCore

Private server integration: export creature spawns, patrol waypoints,
and quest definitions as ready-to-import SQL for AzerothCore/TrinityCore.

- creature_template: name, level, health, mana, damage, armor, faction,
  npcflag (questgiver/vendor/flightmaster/innkeeper), displayId, scale
- creature: spawn position, orientation, respawn time, wander distance,
  movement type (stationary/wander/patrol)
- creature_addon + waypoint_data: patrol path waypoints with delays
- quest_template: title, description, completion text, level, XP, money
- All use ON DUPLICATE KEY UPDATE for safe re-imports
- Auto-exported as spawns.sql alongside other assets on zone save
- File > Export Server SQL menu item for standalone export
- Map ID from zone metadata panel used in spawn table
