feat(post-audit): Phase 1.3 + 1.4 + Phase 2 signals + pulse admin

Phase 1.3 — signing-invitation role copy
- Order-agnostic phrasing (was assuming client→developer→approver order;
  ports configure any sequence so the "client has already signed"
  assumption was brittle).
- Explicit developer-role branch + safe default for unknown roles.

Phase 1.4 — supplemental form per-port URL
- New supplemental_form_url registry entry (email.from section).
- Threaded through getPortEmailConfig → PortEmailConfig.supplementalFormUrl.
- /api/v1/interests/[id]/supplemental-info-request resolves the link
  via per-port URL when set, falls back to /public/supplemental-info/<token>
  CRM route when blank.

Phase 2 — deal-pulse signal expansion + admin config
- Compute function gains:
  - +5 eoi_sent_recent (≤14d) — was previously invisible
  - +15 deposit_received — strongest near-commit signal
  - +10 contract_signed — closed-loop reinforcement until outcome flips
  - -25 document_declined — strongest cooling signal
  - -20 reservation_cancelled — booked-then-cancelled warning
  - -30 berth_sold_to_other — primary berth lost to another deal
- Each signal honours optional per-port `signal_<id>_enabled` toggle.
- Registry adds master toggle (pulse_enabled), per-signal toggles, and
  per-port label overrides (Hot/Warm/Cold rename).
- New /admin/pulse page mounted via RegistryDrivenForm.
- AdminSectionsBrowser entry under Configuration.

Data-wiring for the 3 risk signals (declined/cancelled/sold-to-other)
needs follow-up: requires either schema timestamps on interests or
derivation from event tables. Master plan §B captures the gap.

Tests: 1374/1374 passing. tsc clean.
