feat(skeleton) : wire skeleton writes to SkeletonStructureService

ModelType.setStructure() now stores data in pendingStructure instead of
writing to JSON columns. A new ModelTypeProcessor intercepts API Platform
POST/PUT/PATCH operations and delegates skeleton writes to
SkeletonStructureService, which persists to relation tables.
