Migrate sync objects into ProductionDataBaseSync schema + add permanent audit archive

- Add sql/00_schema.sql: create dedicated ProductionDataBaseSync schema (idempotent)
- Move SyncQueue and usp_SyncApply from dbo into ProductionDataBaseSync
- Add sql/03_sync_log_archive.sql: permanent, append-only SyncLogArchive that
  records both OriginalOperateType and ProcessedOperateType plus the Access log
  OriginalTime, so pipeline divergences (e.g. Insert applied as Delete) stay
  reconstructible forever (SyncQueue is transient and only keeps processed type)
- config.py: inject sync_queue_table / archive_table / apply_proc (default to the
  new schema); SqlWriter takes these names instead of hardcoding dbo
- sql_writer.py: add ArchiveRow + insert_archive_row (dedup on source keys),
  parametrize queue/archive/proc names throughout
- capture.py: archive every consumed log row before enqueue (preserves evidence
  before cleanup deletes the Access log)
- service.py: pass the three names into SqlWriter
- tests: read queue/proc names from config instead of hardcoding dbo.SyncQueue
