When an event has no inline customer_email/host_email but has customer account(s) assigned (event_customer_assignments), the pre-event reminder now sends to those registered customers instead of skipping with no_recipient. Recipients sent to an assigned account are queued WITHOUT eventId so the language resolver uses the customer's preferred_language (vs the event's language for inline-email sends). Applies to both the flow path (sendReminderForEvent) and the legacy pass. The gallery-ready mail deliberately does NOT fall back to accounts — only the reminder does. Test covers the no-inline-email + assigned-customer case.
