feat(post-audit): batch A+B quick-wins + audit-side residuals

Bundles the user-prioritised follow-ups from the post-audit punch-list.

Batch A — pipeline + EOI safety:
 - §1.1 timeline buildAuditDescription renders diff fields ("leadCategory → hot_lead").
 - §4.13 EOI rejection cascade: notification to assigned rep + audit row + rose banner.
 - §4.10b finish doc-detail: SigningProgress reuse, linked-entity names (server-resolved),
   per-event icons + tooltips + show-more in activity panel.
 - §7.2 stage guidance card replaces empty Payments slot pre-reservation.
 - §4.15 deal-pulse trigger audit (docs/deal-pulse-trigger-audit.md).

Batch B — UX consistency + docs:
 - §1.4 quick log-contact button on interest header.
 - §2.1 contact-log compose: Dialog → Sheet.
 - §7.1 docs/deal-pulse explainer page; /docs/ in PUBLIC_PATHS.
 - DocumentStatus now includes 'rejected' + 'declined' across constants, labels, tone maps.

Audit-side residuals:
 - M-NEW-1 /me/ports skips port-context requirement.
 - M-AU03 audit log CSV export endpoint + UI button.
 - M-IN03 dead receipt-scanner.ts deleted; live path already per-port.
 - M-P01 pg_trgm GIN indexes (migration 0071).
 - §10.1 webhook tests verified passing (was stale).

Deferred per user direction:
 - §11.3 email copy refactor (needs old-CRM reference).
 - M-EM03 IMAP bounce-to-interest linking.

Tests: 1374/1374. tsc + lint clean.
