[WIP] Feat/marketing emails (#21173)

Marketing/campaign emails on top of the emailing-domain (SES) feature: send a broadcast to a hand-picked list, with per-customer-domain unsubscribe links and opt-out-only **unsubscribe topics**. ## Model Standard objects (workspace schema, flat-metadata): - `messageCampaign` — a campaign send (subject, body template, from address, status, list, optional unsubscribe topic). - `messageList` + `messageListMember` — the hand-picked audience (person ↔ list join). A campaign's recipients are its list's members; everyone is sendable unless suppressed. Core entities (`core` schema, workspace-scoped — readable by the public unsubscribe flow without a workspace context): - `unsubscribeTopic` — an opt-out-only category (name, description, visibility). There is no opt-in subscription state. - `messageSuppression` — the single consent store: a row with `unsubscribeTopicId` NULL is a global block; a row with an `unsubscribeTopicId` and reason `UNSUBSCRIBE` is a per-topic opt-out. Two partial unique indexes dedupe global vs per-topic rows (Postgres treats NULLs as distinct). - `emailingDomain` — the workspace's SES sending domain, auto-provisioned when an email channel is added (and cleaned up when its last channel is removed), with verification status + DNS records. Campaign messages reuse the existing `message` / `messageThread` / `messageParticipant` model — one outbound `message` per recipient with a `deliveryStatus` state machine. ## Sending - `sendMessageCampaign` resolves the audience **under the caller's permissions**, creates the campaign, and enqueues a single fan-out job (the request never materializes per-recipient rows or jobs). - The fan-out job materializes one QUEUED message per recipient (deterministic ids → idempotent re-runs, reconciles crash-orphaned rows) and fans out per-recipient send jobs carrying **only ids**. - Each send job renders per-recipient `{{variable}}` merge fields and sends via `EmailingDomainSenderService`, which applies suppression (global + per-topic) and the unsubscribe footer/headers. Suppressed recipients are recorded `SKIPPED`. - The campaign finalizes `SENT`, or `SENT_WITH_ERRORS` if any recipient terminally failed. - `previewMessageCampaignAudience` returns a pre-send breakdown (total / without-email / duplicate / globally-unsubscribed / topic-unsubscribed / sendable), shown as a hint under the composer pickers. ## Unsubscribe - Encrypted (AES-256-GCM) token carrying workspaceId, address, optional `unsubscribeTopicId`, `issuedAt`, and a `preview` flag. - One-click POST (RFC 8058) + `mailto:` — topic-scoped when the token carries a topic, global otherwise. - Preferences page: a checkbox per visible topic (checked = still receiving); submitting creates per-topic opt-outs for unchecked topics and lifts re-checked ones (UNSUBSCRIBE only — never `BOUNCE`/`COMPLAINT`, never a global block). - A **Preview** action in settings opens the live page via a preview-claim token; opt-out POSTs are no-ops for preview tokens, so previewing never mutates state. - SES webhooks: inbound unsubscribe + outbound bounce/complaint → suppression (race-safe against at-least-once delivery, with reason escalation that never downgrades). - Per-customer unsubscribe hostname (Cloudflare DNS); sends are gated on it being active, except in LOG/demo mode. ## Architecture Campaign orchestration, suppression, the sender, the unsubscribe controller, and the SES webhook handlers live in `src/modules/emailing` + `src/modules/messaging-webhooks` (the workspace-feature layer). `core-modules/emailing-domain` keeps the SES driver, domain provisioning, the `unsubscribeTopic` / `messageSuppression` core entities, and the unsubscribe token/hostname plumbing. Domain creation is validated (`CreateEmailingDomainInput` — domain-format regex, lowercased) before any value reaches SES or the unsubscribe hostname. ## Frontend - Campaign composer side panel (from / list / unsubscribe topic / subject / body) with a live audience-preview hint. - Email settings: email channels each showing their auto-provisioned sending domain in a single section (status + DNS records + a "Check verification" action), plus an **Unsubscribe Topics** section to create/manage topics and preview the recipient page. A demo-mode banner is shown when the LOG driver is active. --------- Co-authored-by: Félix Malfait <felix@twenty.com> Co-authored-by: Félix Malfait <felix.malfait@gmail.com>
