UPL-proof document templates + reliable bounce sync

Templates (22 files):
- Replace "Reviewed By" with "Document prepared by" + consulting disclaimer
- Add "not a law firm / not legal advice" footer to all CPNI, CALEA, RMD docs
- Change "on behalf of" to "at the direction of" in discontinuance letter
- Reframe RMD penalty language as client acknowledgment

Bounce sync:
- New listmonk-bounce-sync.py replaces unreliable bash tail watcher
- Scans full mail.log, matches QIDs to campaign senders, inserts directly
  into Listmonk DB with proper subscriber_id foreign keys
- Idempotent, runs via cron every 5 minutes
