fix: Sunstrider pin regression, ghost pins, and learner zone normalization

- Fix: isSunstrider block in _MergeSpawnEvidence now checks IsAscensionProtected
  before writing learner data to npcDataOverrides. Without this guard, each Mana
  Wyrm kill overwrote AscensionDB's z1241=5 data with learner z3431 coords.

- Fix: Clustering disabled for zone 1241 (Sunstrider Isle) in _DrawObjectiveIcons
  so all 5 AscensionDB spawn pins display individually instead of collapsing to 2.

- Fix: Ghost pin loop in AvailableQuests.lua -- 'while frames[i]' was iterating a
  string-keyed table with a numeric index (never iterated). Changed to pairs().

- Fix: NormalizeSpawnZoneKey now uses ZoneDB.areaIdToUiMapId for all zones so
  learner evidence is stored under map IDs (e.g. 1241) not area IDs (e.g. 3431),
  matching AscensionDB's key space. Applied in LearnNPC and _StoreGuidSpawnEvidence.

- Fix: isSunstrider detection in _MergeSpawnEvidence updated from hardcoded
  zoneId==3431 check to IsSunstriderNativeZone() since zone IDs are now normalized
  to map IDs at storage time.
