feat(post-audit): Phase 5 partial (4/8 templates) + 7.1 editor scaffold + per-entity reminder buttons

Phase 5 — luxury-port email tone (4 of 8 templates):
- portal-auth.tsx — activation + reset: "It's our pleasure to invite
  you to the {portName} client portal — your private space to review
  your berth, manage signed documents, and stay in touch with your
  sales liaison", sign-off "With warm regards, The {portName} Team",
  subjects "Welcome to {portName} — activate your client portal" /
  "Reset your {portName} portal password".
- inquiry-client-confirmation.tsx — "We've noted your enquiry, and a
  member of our team will be in touch shortly through your preferred
  channel", "should anything come to mind in the meantime", sign-off
  "With warm regards, The {portName} Sales Team".
- notification-digest.tsx — "Your {portName} update" header, "Here's
  what's waiting for you", "With warm regards, The {portName} Team".
- document-signing.tsx — all 4 sign-offs ("Dear X, ... Thank you, The
  {portName} team") rewritten to "With warm regards, The {portName} Team"
  with capitalised Team for consistency.
- Voice captured from old-CRM Nuxt repo
  (/Users/matt/Repos/Port Nimara/Port Nimara Client Portal/client-portal/
  server/utils/signature-notifications.ts) which already used "Dear",
  "Best regards", and collective sign-offs.

Remaining 4 templates (admin-email-change, crm-invite,
inquiry-sales-notification, residential-inquiry) + cross-port snapshot
tests queued as follow-up.

Phase 7.1 — PDF editor scaffold:
- New admin route /admin/templates/[id]/editor/page.tsx wired to a
  client-side <TemplateEditor>.
- Renders page 1 via react-pdf (worker URL pattern mirrors
  components/files/pdf-viewer.tsx); click-to-place markers in percent
  coordinates so a future page-size swap doesn't shift placements.
- Token picker over VALID_MERGE_TOKENS (sorted).
- Save persists overlayPositions via PATCH against the existing
  document_templates row; validator accepts the new field via
  fieldMapSchema from lib/templates/field-map.ts (no migration needed
  — overlay_positions JSONB column already exists).
- Outer/inner-body split + key-by-templateId remount avoids the
  in-render setState antipattern when seeding from server data.
- Add + delete markers supported. Multi-page, drag, resize, preview,
  new-PDF upload all defer to 7.2.

Per-entity polish:
- [+ Reminder] button on yacht / client / interest detail headers,
  threading defaultYachtId / defaultClientId / defaultInterestId so the
  ReminderForm opens with the entity pre-linked.
- [EOI] badge on yacht detail header when yacht.source === 'eoi-generated'
  (mirrors the contacts-editor pattern shipped in eaab149).

Phase 6 hardening:
- imap-bounce-poller strips whitespace from IMAP_PASS so Google
  Workspace App Passwords (16-char "abcd efgh ijkl mnop" format) work
  whether pasted with or without spaces. Confirmed via Google docs that
  the visual spaces are formatting only and must not reach the IMAP
  server.

Quality gates: 1374/1374 vitest, tsc clean, lint 0 errors.
