Fix three timer-pause gaps found in code review

- pauseDraftOnError now calls onDraftPaused() before emitting so the
  error-path pause carries the same snapshotted timer data as the
  manual-pause route (fixes inconsistency between the two paths)
- Parallelize DB updates in onDraftPaused with Promise.all instead of
  sequential awaits
- Extract clientExpiresAt() helper to draft-timer.ts and use it in all
  three places that re-anchor timeRemaining to the client clock, replacing
  duplicated Date.now() + timeRemaining * 1000 expressions
