Simplify: typed status, skip-write guard, remove redundant comment

- Use ImportBatchStatus type instead of raw string literals in sweep job
- Add a COUNT pre-check so the sweep UPDATE is skipped when no stale
  batches exist (avoids an unconditional write every minute)
- Remove comment in disconnect route that explained what the code does
