feat(emails): sales send-out flows + brochures + email-from settings

Phase 7 of the berth-recommender refactor (plan §3.3, §4.8, §4.9, §5.7,
§5.8, §5.9, §11.1, §14.7, §14.9). Adds the rep-driven send-out path for
per-berth PDFs and port-wide brochures, the per-port sales SMTP/IMAP
config + body templates, and the supporting admin UI.

Migration: 0031_brochures_and_document_sends.sql

Schema additions:
  - brochures (port-wide, with isDefault marker + archive)
  - brochure_versions (versioned uploads, storageKey per §4.7a)
  - document_sends (audit log of every rep-initiated send; failures
    captured with failedAt + errorReason). berthPdfVersionId is a plain
    text column (no FK) — loose-coupled to Phase 6b's berth_pdf_versions
    so the two phases stay independent.

§14.7 critical mitigations:
  - Body XSS: rep-authored markdown goes through renderEmailBody()
    (HTML-escape first, then a tight allowlist of bold/italic/code/link
    rules). https:// + mailto: only — javascript:/data: URLs stripped.
    Tested against script/img/iframe/svg/onerror polyglots.
  - Recipient typo: strict email regex + two-step confirm modal that
    shows the exact recipient before send.
  - Unresolved merge fields: pre-send dry-run /preview endpoint blocks
    submission until findUnresolvedTokens() returns empty.
  - SMTP failure: every transport rejection writes a document_sends row
    with failedAt + errorReason; UI surfaces the message.
  - Hourly per-user rate limit: 50 sends/user/hour via existing
    checkRateLimit().
  - Size threshold fallback (§11.1): files above
    email_attach_threshold_mb (default 15) ship as a 24h signed-URL
    download link in the body instead of an attachment. Storage stream
    flows directly to nodemailer to avoid buffering 20MB+.

§14.10 critical mitigation:
  - SMTP/IMAP passwords encrypted at rest via the existing
    EMAIL_CREDENTIAL_KEY (AES-256-GCM). The /api/v1/admin/email/
    sales-config GET endpoint never returns the decrypted value — only
    a *PassIsSet boolean. PATCH treats empty string as "leave unchanged"
    and explicit null as "clear", so the masked-placeholder UI round-
    trips without forcing re-entry on every save.

system_settings keys (per-port unless noted):
  - sales_from_address, sales_smtp_{host,port,secure,user,pass_encrypted}
  - sales_imap_{host,port,user,pass_encrypted}
  - sales_auth_method (default app_password)
  - noreply_from_address
  - email_template_send_berth_pdf_body, email_template_send_brochure_body
  - brochure_max_upload_mb (default 50)
  - email_attach_threshold_mb (default 15)

UI surfaces (per §5.7, §5.8, §5.9):
  - <SendDocumentDialog> shared 2-step compose+confirm flow.
  - <SendBerthPdfDialog>, <SendDocumentsDialog>, <SendFromInterestButton>
    wrappers per detail page.
  - /[portSlug]/admin/brochures: list, upload (direct-to-storage
    presigned PUT for the 20MB+ files per §11.1), default toggle,
    archive.
  - /[portSlug]/admin/email extended with <SalesEmailConfigCard>:
    SMTP + IMAP creds, body templates, threshold/max settings.

Storage: every upload + download goes through getStorageBackend() —
no direct minio imports, per Phase 6a contract.

Tests: 1145 vitest passing (+ 50 new in
markdown-email-sanitization.test.ts, document-sends-validators.test.ts,
sales-email-config-validators.test.ts).
