Fix NPC movement animation sync and minimap marker behavior

- Use interpolated moveInstanceTo() for normal server NPC position deltas so walk/run animations play instead of visual sliding
- Keep hard snaps only for dead units and large corrections/teleports
- Add per-creature render position cache to drive interpolation safely across frames and clear it on spawn/despawn/reset
- Keep minimap controls visible regardless of quest-status availability
- Correct minimap NPC/quest marker projection mapping to match minimap shader transform
- Add optional nearby NPC minimap dots setting (default OFF), exposed in Gameplay > Interface and persisted in settings
