fix(learner): learner-only mode shows only learner data

Three-mode spawn-merge semantics:
- Learner: discard npcDataOverrides (which AscensionDB's _Asc_MergeInto
  populates with curated coords). GetNPC returns learnerRecord only.
  _ApplyNpcLiveUpdate and object-spawn injection use IsAscensionProtected
  (mode-dependent) so learner coords pass through in learner mode.
- Auto: static DB primary, learner fills gaps. Curated spawns protected.
- Static: base DB only.

Also removes the allowSpawnMerge bypass that was the original hole
letting learner coords leak into curated spawns in auto mode.
