Per PRE-DEPLOY-PLAN § 1.3.7. Lays the foundation for admin-configurable
routing of every outbound email category to either the noreply or
sales sender account.
Pieces shipped:
- `src/lib/services/email-routing.ts` — EmailCategory enum (17
categories covering every shipped surface), DEFAULT_CATEGORY_ROUTING
map (auth/notifications/EOI-invite → noreply; brochure/PDF/sales
send-outs → sales), `resolveSenderForCategory()` + a graceful
fallback to noreply when the resolved sender is sales but creds
aren't configured.
- `GET / PATCH /api/v1/admin/email/routing` endpoints — gated on
`admin.manage_settings`. Returns the routing + sales-availability
flag + canonical category list.
- `EmailRoutingCard` — matrix UI dropped into /admin/email below the
sales-email-config card. Per-category dropdown auto-disables the
`sales` option when the port has no sales SMTP creds; explains the
state in an amber callout. Save-on-change with toast + "Reset to
defaults" button.
Setting persisted as `system_settings.email_routing` (JSONB blob).
Followup: opportunistic migration of existing dispatchers (sendEmail,
createSalesTransporter callers) to use `resolveSenderForCategory()` —
the defaults preserve current behavior so this is non-blocking.
