Two fixes for QuestieLearner real-time pin rendering:
1. _MergeOverride now skips empty tables (IsEmptyTable guard).
QuestieLearner stores spawns={} before any coords are captured.
Previously _MergeOverride treated {} as valid data and replaced the
base DB's real spawn coordinates with an empty table, breaking pins
for all NPCs that had been seen but not killed (mouseovers, etc.).
2. _InvalidateSpawnListsForNPC triggers after LearnNPC adds new spawn data.
The quest objective system caches spawnList once per objective.
When a kill adds new coordinates, the cached list is stale.
The new helper:
- Scans all active quest objectives for references to the NPC
- Clears objective.spawnList and objective.AlreadySpawned
- Calls QuestieQuest:UpdateQuest to rebuild pins with fresh data
This makes learned pins appear in real-time without /reload.
