refactor(lite): remove dead parallel refresh/readiness scaffolding (~3.1k lines)

The lite-wallet tree carried a second, unused refresh+readiness architecture
that never reached the shipping binary — exactly the churn CLAUDE.md warns
against. The live refresh path is controller -> gateway.refresh ->
mapLiteWalletRefreshResult -> applyLiteRefreshModelToWalletState; this parallel
stack was dead weight.

Verified unused (their public types/functions are referenced only within the
cluster), then deleted (8 files / 16 incl. headers):
- lite_wallet_refresh_service            (LiteWalletRefreshService + gateway adapters)
- lite_wallet_app_refresh_coordinator
- lite_wallet_app_refresh_orchestrator
- lite_wallet_refresh_readiness_policy
- lite_wallet_state_apply_plan
- lite_wallet_state_apply_executor
- lite_wallet_sync_app_refresh_integration
- lite_wallet_sync_execution_readiness

Severed three thin couplings into the cluster from live files:
- state_mapper: dropped the dead mapLiteWalletRefreshServiceResult and switched
  its include from refresh_service.h to gateway.h (where the live
  LiteWalletRefreshResult/Bundle DTOs actually live).
- server_lifecycle_readiness: dropped the unused syncLifecycleInput member +
  converter and the sync_app_refresh_integration include.
- artifact_resolver: relocated the three LIVE artifact-input structs
  (LiteWalletSdxlArtifact{Symbols,}Input, LiteWalletLinkedBackendReadinessInput)
  out of sync_execution_readiness.h — their only real consumers — into
  artifact_resolver.h, then dropped the include.

Also removed the dead DRAGONX_LONG_LITE_BATCH CMake machinery (its source var
was empty; on Windows it generated a broken lite_batch90_receipt_plan.cpp that
#included an empty path) and the stale .cpp/.h entries in CMakeLists.

Lite source files: 44 -> 30. Lite + full-node configure, both targets build,
test suite passes, source-hygiene clean.
