feat(sub): add Incy client integration and routing tab

Add an Incy quick-import button (incy://add) to the Android and iOS app menus on the subscription page, and a new Incy settings tab with routing enable + rules. Incy routing is delivered by injecting an incy://routing/onadd line into the raw subscription body, avoiding a collision with Happ's Routing header. Includes backend settings, regenerated OpenAPI/zod schemas, and translations for all locales.
