v9.18.0 — Tabbed Emails settings page

The admin Settings → Emails page is now split into Sender and Templates tabs (shared Tabs component), so the two concerns are separated and the page is shorter. The sender form's bordered card is dropped in favor of the tab grouping, and the redundant "Templates" sub-heading is removed. The template-edit dialog is unchanged.

No consumer action required

Purely a UI reorganization of an existing admin page — no data model, Firestore, or API changes; existing email settings and templates render unchanged.
