fix(quest): require multi-position learned spawns before overriding AscensionDB

- Add local _CountUniqueSpawnPositions helper (counts unique {x, y}
  across all zone buckets in a spawn table).
- Gate the prioritizeMyData check on ld.settings.enabled, matching the
  Database/QuestieDB.lua fix — when the learner is fully disabled,
  the override lookup is skipped entirely.
- Replace the NPC-15274-specific debug print in the monster() spawn
  selector with a universal reliability check: the learner data is
  only used when CountUniqueSpawnPositions(learnedSpawns) > 1.

This is the consumer-side enforcement of the QuestieLearner cleanup
(commit e71e072). Singleton-position spawn entries are typically the
player's current position captured during quest dialog (accept/turn-in)
rather than real kill evidence. By requiring at least 2 unique
positions, we avoid letting that pollution clobber AscensionDB curated
spawn data.

The NPC-15274-specific debug print was removed — the universal check
replaces it, and the diagnostic it provided is now expressed through
the Questie DEBUG_DEVELOP log line (which still emits when the new
condition is met).
