feat(email-group): communications UX, per-record DNS status (#23002)

- Rename Communications label to singular, remove docs-home banner
- Provision unsubscribe Cloudflare records at domain creation and
surface per-record status badges; skip Cloudflare when not configured
- Move sending-domain status into the section header and only show the
records table when a record is unverified
- Reply to the original recipients when replying to your own message
- Fix DNS records table column/badge alignment; emit synthetic records
in the log driver for local testing
