fix(Sunstrider): correct map pins, override check, nil guards

- zoneDB: remap areaId 3431 → uiMapId 1241 (Sunstrider Isle) so quest 8335
  pins render on correct map instead of Eversong Woods (1941)
- compat/HBD: remove 1241→1941 redirect (Sunstrider pins now handled by zoneDB)
- compiler: QuerySingle override check skips empty tables (next() guard) so
  spawn data overrides don't fall through to nil base DB values
- MapIconTooltip: nil guards for minLevel/maxLevel to prevent crashes
- Map/QuestieMap: remove stale 1241→1941 redirect comment
