Fix taxi flight: camera panning, world reload, gryphon display, and animations

- Clear introActive/idleOrbit in externalFollow block so mouse panning works during taxi
- Skip full world reload on same-map teleports (taxi landing) by tracking loadedMapId
- Collect all model IDs for a path when resolving gryphon display ID (fixes displayId=0)
- Remove incorrect MountDisplayId fields from Vanilla/Turtle TaxiNodes DBC layouts
- Add Vanilla fly animation IDs (234/229/233) to taxi mount animation candidates
