Two of the six Phase 6 polish items shipped in one commit because they
share the data + plumbing path (per-doc message uses the signing-
progress UI's existing layout).
1) Signing-progress activity badges
- Surfaces `invitedAt`, `openedAt`, `lastReminderSentAt` (all
populated by Phase 1+2 webhook handlers) per signer in the
existing progress widget. Each badge renders as
"Invited 2 hours ago / Opened yesterday / Reminded 3 days ago"
via Intl.RelativeTimeFormat.
- Resend button: was silent on success/failure; now uses
useMutation + toast so the rep sees whether the reminder fired
or fell into a cadence cooldown. Honours the existing
sendReminderIfAllowed return shape (`{sent, reason}`).
- Title-tooltips on each badge show the exact ISO timestamp.
2) Per-document custom invitation message
- New `documents.invitation_message` column (migration 0060;
applied via psql per the dev-flow note in CLAUDE.md).
- Textarea in UploadForSigningDialog step 2 (recipient configurator),
1000-char cap, placeholder text shows the expected tone.
- custom-document-upload.service accepts `invitationMessage`,
trims + stores on the documents row.
- sendCascadingInviteForNextSigner now reads
doc.invitationMessage and passes as customMessage so every
cascaded recipient (developer / approver / witness) sees the
same note — not just the first signer.
- send-invitation route (manual resend path) reads the same
column → customMessage so manual reminders match.
- The email template's existing customMessage rendering does
the XSS escape; no other plumbing needed.
Phase 6 items still deferred (each ~2-3h, mostly independent):
- Auto-send delay (`eoi_send_delay_minutes` setting + scheduled
BullMQ job — needs a scheduler hook).
- Document expiration (`documents.expires_at` + Documenso
`expiresAt` passthrough — needs Documenso v2 endpoint shape
verification).
- Failed-webhook recovery admin UI (the BullMQ DLQ exists; needs
an admin page with Replay button).
Tests: 1340 → 1350 ✅; tsc clean.
