- 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
